If you really want Chucky, I think both of:

Nylander for Galchenyuk

Nylander and Kessel for Galchenyuk and Schwartz,

Are decent/even. In multicat, Schwartz and Kessel are probs pretty even, and Nylander might have a theoretical higher upside than Chucky, but who knows how far away he is, and I think his upside is capped by the presence of Matthews.

I wouldn't be thinking of trading draft picks. Both your guys farms look pretty weak (no offense). How many teams are in your league?
