One of the upsides to trading perk was allowing us to re sign BBD next season. I'm sure this has been brought up, but after this season was over, Danny and crew would pretty much have to choose between the two. At the trade and still now, I believe keeping Baby over Perk was a better idea (IF we do resign him).
As to the OP idea, Regardless of the O'neals coming back next season, we need size in the frontcourt. Size that at least has some athletic ability (a few fudged lay ups are allowed

). But ya, if Baby walks, we loose alot in his absence. Keeping Green will still give us scoring of the bench but he cant be a primary backup 4. I know BBD thinks hes a starting caliber player that deserves $$$$$ (remember 2 summers ago when he was ranting about why the C's havn't resigned him yet?) but even if he has peaked (I don't believe so), we need him as our back up 4 and starter for injuries (Post KG?, idk)
As for a sign and trade, how much would we offer him ($$$), and with that amount who could we get back? Do we find a legit 4 to replace KG (retired, lockout), or do we look elsewhere, starting center, multiplayer deal?
Sorry for ranting, I'm still getting used to posting. TP appreciated
