The auction would start:

1, (2), 2, (Pass); 3, (Pass), 3, (Pass); 3NT, (Pass), 4, (Pass)

Continuations will now depend on your slam methods (Kick-back / Minorwood / Cue-bidding), but all roads lead to 6.

West is far too strong for a 2 free bid here. Obviously, it all depends what you have agreed with partner about what a 2 bid means here? If 2 is game forcing then Tramticket's auction is fine. Otherwise, if using free bids, typically, 5+ s (8-11 hcps) then I prefer Double with the West hand instead of 2.

For me (playing Acol, but also in other systems), you can't be too strong for 2, which is 10+ HCP and forcing for one round. The 3 rebid then creates a game force and you can comfortably rebid 3 (it must be right to make a second heart bid before supporting clubs).

Our auction would probably just go:

1, (2), 2,, 3,, 4,, 4,, 4,, 4,, 4NT,, 6

where 2 is invitational+ (would be game force without the interference), 3 creates game force, 4 fixes trumps and requests control-bids and 4NT shows an even number of Key Cards.

Would you give up on hearts so easily?

Reluctantly but yes.
With partner bidding 3, it's quite likely that N has the hearts, in any case the chance to control bid from a decent level in a known fit is now or never.

The key agreements here are: how strong is 2!H, is 3!C game forcing, does 4!C set the suit and make a skam try.

If 2!H is forcing then i would raise 3!C to 4!C as a slam try in !C. Having the agreement that 4 of our minor is always a suit setting slam try is worth its weight in gold.

For me 2!H is 8+ but still a 1 round force. X and 3!D both highlight how problematic a non forcing 2!H can be.

Are you sure about this? If 2 is forcing, surely a minimum opener is forced to bid a second suit if he has one.

My methods are different, as I play transfers over interference.
East . . . . . . West
1 (2) X
3 ...
Opener would bid 2 as requested if he would pass a non-forcing response, so 3 here not only denies hearts (could bid 3) it also shows a strong hand and is GF with at least 4 clubs.
... 4
4(asking) - 4(2 of the 6 crucial cards
6

I would open 1 rather than 1 (we do so on a couple of hand types, this being one, in an uncontested auction 1 followed by 1 then 2 shows this hand type for us, the other is the same without KQ where we bid 1 and follow up with a jump to 2) at which point 1-(1/2)-2/3 shows this hand type and we're not stopping.

On your auction, I think I just ask aces (4 for us) and bid 6 opposite 2+Q

Yes, I am sure (for us), opener has made a high-level reverse - no different from an uncontested auction. Indeed, the 2D interference hasn't really inconvenienced our auction.

A minimum opener should make the same rebid that they would have chosen in an uncontested 1S, 2H auction - often 2S.

You seem to assume the agreement of non-forcing free bids (and not for the first time) which are highly alertable, rarely alerted on BBO, mostly by players that don't know this and in my experience otherwise rarely played. You will note that it is not alerted in the bidding diagram.

If west fails to support clubs either immediately or after bidding 3 first they have committed a deadly sin imo and whatever your methods are after that I can't imagine not getting to the slam.

If you can't bid a 1-round forcing 2H here, you need to change your system.

Also, why are you so quick to use RKCB when (a) we might still have a heart fit - partner only needs QX in the suit - not unreasonable and (b) a double fit might make us consider a grand slam or 6H/6NT? (particularly if MPs).

Because the length of the hearts and club fit make the double fit irrelevant, they can be ruffed out if all the controls are there but you'd better be playing 4130 as one control is not enough and you're beyond 5 if partner has 3xKQJ.
