I was reading the other thread with interest since I don't particularly like bidding the same way with 54/45 in the minors. First thought was that rhm's structure is nice (promising 5C) but then we have no good rebid with 5D4C and 15-17. We could adopt awm's structure since we deny 15+ with clubs:

1D-1S; ? (for simplicity)
1NT=11-14 balanced (5332 always, optionally on 2443/3442)/1345/2245/optionally
2254
2C=5+D, 4+C, 11-17 (but see 3C)
2S=can be 3 if unbalanced

But it just feels a bit strange not to mention the clubs not even the second round of bidding... Is there any other way?

Finally, if we bite the bullet and bid 2C with both relative lengths, are there any clever follow ups or something we should know?

Background info:
1NT is 15-17 (5422's normally included, except if both majors)
1C/1D is optional on 4 diamonds and a weak NT (but 1D is mandatory on 5D332).
1C can contain 15-17 with 4D5C (as opposed to Matula)
1D-1S; 2C-2H is a puppet to 2S, to play or GF.
