Berg and Wilson for pick 11 - I'd take that.Would something like this work?
Adelaide 1st pick + Collingwood 2nd pick to GWS
Treloar to Collingwood
Scharenberg + Hampton/Wilson to Adelaide
So
Adelaide trade 1st for Scharenberg and Hampton/Wilson
Collingwood trade Scharenberg and 2nd for Treloar
GWS trade Treloar and Hampton/Wilson for Adelaide 1st and Collingwood 2nd
