You could play 4-way transfers:
2♠->clubs
2NT->diamonds

or, if you want 2NT as a natural invite:
2♠->clubs, or invitational with diamonds
3♣->diamonds, either weak or slamish

If you need both 2NT and 3♣ for other purposes so that all weak or slamish minor 1-suiters go into 2♠, then maybe (I am just making this up):
2♠, then 3♥: slamish with clubs
2♠, then 3♠: slamish with diamonds
2♠, then 3NT: 5-5 minors, nonforcing but some slam interest
2♠, then 4♣: 5-5 minors, opener now sets trumps with
.....4♦->clubs,
.....4♥->diamonds

4N  becomes your ♥ cue bid.

Indeed, but that's rather less useful than a 4♥ cue-bid. Over 4♥ partner can bid 4♠; over 4NT he can't.

True, but, if you have the agreement that 4♥ is kickback and 4NT replaces the heart cue bid, you cue bid spades before hearts. Bypassing 4♠ to cue bid 4NT (hearts) implies no spade control.

So:
- We can't cue-bid spades and then bid Keycard
- We can't cue-bid hearts, cue-bid spades and then bid Keycard

If your system (2s first response) is a given, then Helene's point that 4m not only sets trump, but also is minorwood makes total sense. U don't need a minor raise to know you have a fit because of the NT opening bid.

Opener should not be the one in charge of this auction, so KB from that side is not a good idea.

These things don't seem to come up in MSS or Walsh Relay auctions, but that is a whole new hijack.
