How about this over 1♥, just an idea:

X shows 4♠ or strong with 5♠
1♠ is a NT response
1NT shows 5♠ NF
2m natural forcing
2♥ showing 6+♠
2♠ INV+ raise of minor

Edit: raise to 2 of partner's minor is just competitive

That seems quite sensible. Alternatively, you might try

X shows 4♠ or weak with 5♠
1NT shows 5♠ F1
