It's possible, but from what I have read spontaneous combustion is possible too in certain situations... So......
Give me a reason why you want Hedo, and what his role would be on this team.. Also with that other guy you mention..
You know, I would like Lebon at SF, KG at PF, Deron Williams at PG, Kobe at SG, and Howard at C.. But Wanting and discussing how to get said players are two different things. Rather than ask us if it's possible ask yourself how it could be possible and then post it!
