2♣ Stayman
2♦ Transfer to hearts
2♥ Transfer to spades
2♠ Transfer to clubs
2NT Transfer to diamonds
3♥ 31(45)
3♠ 13(45)
3NT To play
4♦ Transfer to hearts
4♥ Transfer to spades
and that 5-card major 5332s in range are systematically opened 1NT, what would you prefer to use 3♣, 3♦ and 4♣ as?
(I'm interested in 14-16 but go ahead and pretend it's 15-17.)

(1) You need a way to show an invite with 5/5 majors, assuming 2♥...3♥ is forcing.
(2) You need a way to show a strong hand with 5/5 minors (assuming transfer-other minor is shortage).
(3) You need to be able to find 5-3 major fits when responder has minor suit shortage.
The 5/5 minors weak hand is rare and can be handled via 2NT as others have said. There are various ways you can prioritize the three things above. I think my preference would be:
(1) 3♦ shows 5/5 majors invite or GF w/o slam interest. With a slam try, bid 2♥..3♥.
(2) 3♣ shows a strong hand with both minors. Over this 3♦ agrees diamonds, 3M is a cue for clubs, 3NT suggests playing there.
(3) With this hand type, bid 2♣ and then some structured follow-up. A simple option might be that 3m after stayman shows shortage w/o a known major fit.

Hm, I dunno, I kind of like 3m natural and forcing after Stayman...

3♦ = interest in slam, either 4-1-4-4 or 1-4-4-4. Opener bids cheapest 4-card suit to cooperate or 3NT with a bad hand for slam.

I play the above except that 4♣ is strong with both majors. Also I play a weak NT, so I don't mind whether 5-card Stayman is puppet or not. It is a little more flexible if it is not, I think.
Since one must have Gerber even though one never uses it, we have 4♠.

I use them to show 3/4 in the majors, a stiff in the bid minor, and a 5 card suit in the off minor. I also put 6-3-3-1 in that structure.

The meaning for 3♦ depends a lot on what you can do with the rest of your system. I think strong minor oriented hands are a problem in many systems so it might be a fix. If you have absolutely no idea what to do with it, I'd give multi-invite a try (invite with 6+M, M unknown, respond like after a multi-2♦ opening). This way, you can bid 1NT-2♦/♥-2M-3M as balanced slam try which gives you an entire level of cuebidding.
4♣, well, you can do a lot of things. I've played Gerber for so long, but I've never used it. So you might as well switch to Texas, which leaves responder the choice who gets to play 4M.

1NT-3♣
3♦-3♥*
3NT
is a better auction than
1NT-2♣
2♥-3NT

I guess there will be some backlash now that in this case we should alert and/or prealert all our stayman auctions from now because of possible negative inferences.

Hey, I agree that gerber must not be optimal and something must be better. That said, I've never seen a good use for it over 1N (for 2N definitely) if you're also playing texas. I like 4C showing hearts and 4D showing spades a lot, though I admit when I played it with one partner it gave me anxiety since I have played Texas my whole life lol. For instance strong with both majors doesn't seem that useful, since I would transfer to spades and bid 3H and have more room. Maybe 4C both majors and not slammish to ensure we rightside it, and freeing up 2H 3H as always slammish might be useful. I dunno.
Amusingly my partner bid gerber today and it was the first time I had seen it in a while.

Some people find this debatable and indeed it is, but I am a big believer.
1N 3c 3D (saying nothign about 4 card majors...it doesn't need to, with 4-4 majors you bid normal stayman), compared to stayman thhen 3N:
-The defense knows whether the 1N opener has 4 card major or not.
-If opener shows a 4 card majors, the defense knows before it leads that opener has 4+ of that major, and responder has 4 of the other major.
-If opener does not have a 4 card major, the defense does NOT know which major dummy is going to hit with.
As opposed to:
-The defense does NOT know whether opener has 4 of the other major.
-The defense always knows before it leads what dummies 4 card major is.
So basically, it is possibly worse to bid 1N-2C-2D-3N than 1N-3C-3D-3M, because they know which major dummy has, but it's probably not since they won't know whether opener has 4 of the other major in the latter auction. However, it is much better to bid 1N-3C-3D-3M-3N than 1N-2C-2M-3N, since the defense knows about both majors.
That being said, puppet sometimes loses when they can double an artificial 3M bid, and sometimes lets the defense know that opener has a 5 card major rather than the 4+ they'd know over no stayman. IMO bidding 3C with all hands with 4M choice of games is a big winner though.

Why that need for an invite with 5/5 majors? 1nt-2♣-2♦-2♠-2nt-3♥ already shows that hand...

While I find that a reasonable use of this sequence, I'm sure other people have different plans for it... Stayman followups can be a true minefield. And of course, using a minor-suit bid to show 5-5 majors guarantees that you can play from the NT opener's side, which is usually an advantage.

Depends a lot on the meaning of 3♦. If it just denies a 5 card Major, then you're right. But if it promisses at least one 4 card Major (standard Puppet Stayman) you've made your auction longer with a better opportunity for opponents to Dbl for the lead, and opps know the same information about our hands in both sequences.
