Okay here is my completely unrealistic proposal that likely doesn't happen but it's fun to speculate about.
Leafs have supposedly been willing to move on from Carlo who wasn't a great fit and Buffalo was rumored to have interest in return for Peterka.

Then you have the Leafs having interest in Andersson, and Owen Power supposedly being unhappy with his role and fit in Buffalo (Dahlin and Byram forcing him to play his offside on the RH side).
Sabres were rumoured to also have interest in Zary for Cozens last year.
Trade 1: Andersson + Kerins for Carlo + Cowan
Trade 2: Carlo + Zary + 2026 2nd for Owen Power
So you turn Andersson + Zary + 2026 2nd into Power + Cowan.
