Sorry to piggy back on your trade, but I was thinking that Martin would need 30mpg to be successful, and with Toronto it would be difficult with DeRozan, Ross and Fields at the wings.
Utah on the other hand needs a SG, so how about this:

Raptors receive: Millsap, Motiejunas, Bell
Utah receives: Martin
Houston receives: Bargnani
Raja Bell has been on the outs with Utah so including him in the deal shouldn't be a concern (and his contract allows the transaction to work). He'd be a nice veteran guy that plays defense and can shoot the long ball and is an expiring contract. We can buy him out if he doesn't want to play here. Millsap can get you 16ppg so shouldn't be too difficult to make up most of Bargnani's points - plus he's an expiring contract. Utah gets Martin who also has the expiring contract.. but they would then free up room for Favors/Kanter to get more minutes with Millsap gone. Motiejunas is also thrown in for the Bargnani trade. Although I'd rather have the lottery pick back instead of Motiejunas but I don't see us being able to get both.
