More Musical instruments in future packs?

Other than a Sax, which would be cool, I don't fancy many more instruments unless musicians can form a band and instruments joining in on the same songs. I'd accept 5-6 songs to play together, it's okay if they skip adding this possibility for all existing music pieces.

*Imagining Vlad playing his pipe organ while daughter Bonehilda (not the maid version) accompanies him on her Sax* ugh... maybe not...
