I'd be tempted to be putting some kind of big 5-5 hand with the minors into 2NT (or alternatively, some other hand type that really isn't likely to want to declare NT)

We use it (in a structure where all balanced hands opened 1♦ get a wide range 1N rebid) to show an unbalanced GF.
Partner rebids 3♣ unless he has a 7 card suit or 2 5 card suits not including clubs.
Over 3♣: (assuming 1♦-1♠-2N-3♣)
3♦ diamonds only or 6♦/3♠
3♥ 5+♦/4+♥ really big, thereby limiting the simple reverse, not denying 3♠
3♠ 3154/3055
3N 5♦, 4-5♣ not 3♠ or 4♥
4 level rebids show 4 card support for partner and at least 5♦ (option whether you bid the stiff or the fragment)

I don't need 2N for that since 2M-1 is a 3 card raise. I suppose it could be some super strong variant as 1D 1s 2h 2S/2N 3D wouldn't be forcing.
I used to play it as some sort of monster raise with jacoby responses (sort of) but this was with echognome.

- you also play 2S as artifical after 1D-1H
- you play T-Walsh with an artificial 2NT rebid
We play approximately the same structure after 1C-1red-2NT as after 1D-1M-2NT for ease of memory, except that the latter can't have 18-19 balanced in it (and the former can't have a single suited game force). This means it's a strong 4-card raise of various types, or a single-suited game force, or a 3-6 game force. This is not quite best, but it is only one set of artificial rebids to learn for sequences that are not that common.

Right now 2S is natural. 1C 1 red 1N covers all 17-19 balanced.

A strong one-suited hand with 3 card support. There are at least 3 "natural" ways of handling this hand type but none of them are particularly satisfactory.

We currently play another method: a 4 card raise and 16+ hcp. 3C is now a GF relay:
3D = No SPL
3H = Short clubs
3S = Short other major
3NT = Good 6+ diamond suit

Game invitational hands with 6D 3M bid 1D 1M 2C 2D 2M. GF hands with 6D 3M bid 1D 1M 2M-1 2M 3D.
Starting to love the flexibility of this method.

When I played transfer rebids by Opener over 1♣-[1M-1](= 4+ M) and 1R-1M,
1♣-[1M-1]; [2M-1] = weak-or-inv 3 c raise
1R-1M; [2M-1] = weak-or-inv 3c raise
so that
1♣-[1M-1]; 1♠(= trf ♣); 2♣; 2M = 3M(5)6+C, extras but < inv
1R-1M; [2R-1](= trf R)-2R; 2M = 3M(5)6+R, extras but < inv,
1♣-[1M-1]; [2M-1]-2M; 3♣ = 3M6+C, inv
1R-1M; [2M-1]-2M; 3R = 3M6+R, inv
and
1♣-[1M-1]; 1♠(= trf ♣); 2♣; 3M = 3M6+C, FG
1R-1M; [2R-1](= trf R)-2R; 3M = 3M6+R, FG

This begs bigger questions. What do simple auctions in your methods mean, like 1C 1h 1s and 1C 1h 1N?

Several jump shifts are available, for these, for BWDH, for artificial raises. Pick which 4 you think are most important:)

3♣: 4M GF (then 3♦: 6♦3M NF & 3M: 4M 16-18)
3♦: 4M NF
3♥: 5M NF
3♠: 5M GF
1♦ - 1M - 3M: 19+ support
