I would take 2NT after the DBL as to play.
As usual, it seems strange to play this as "to play", or even as INV. Imo you should play Lebensohl here. This way you can distinguish between a garbage stayman and stronger hands, with or without ♥.
For example (quickly invented, so it may have some issues):
Pass = converting to penalty
2NT = Lebensohl
...3♣ = obligated
......pass = weak hand with long ♣
......3♦ = garbage stayman with (4)5+♦, probably 3♥
......3♥ = garbage stayman with 4♥
......3♠ = GF without ♥ fit and without a clear call?
3m = natural and forcing, can still have ♥ imo
3♥ = INV, 4♥
3♠ = GF with 4♥?
