I have a "Multi-Reverse" of 2S over 1H response ( GGG = Gnasher's Gameforce Gadget)
You could combine GGG with Frances' suggestion:

If I played a gadget (which I do) I would use it (2S-2NT-3D = 3-6 invite)
to form GiGGle (Gnasher's invitation + Gameforce Gadget lightly edited)
1♦ - 1♥
2♠! ( may be artificial )
..... - 2NT! ( asks )
??
...3♣! = 4s, no 3h, GF
...3♦ = 3h, 6+d, INV
...3♥ = no 4s, 3h, 5+d, GF
...3♠ = 4s and 3h, GF
...3N = 6+d, no 4s, no 3h, GF
If you agree to play an unbalanced diamond opening then you also free up a 2NT rebid, which can then be used (inter alia) to differentiate between hands with and without 3 card support instead.
