I anticipate Pekovic being traded eventually. However, I don't think he's a great fit on a Boston team that's playing Sullinger and Olynyk at the 4. Pekovic is a guy best paired with an Ibaka, Henson, or Sanders type - a guy who can actually protect the rim. The Love/Pekovic combo wasn't extremely effective because those two guys aren't great rim protectors and you'd have the same issue with Sully/Olynyk and Pekovic.
I think you touch upon a good fit in your post, maybe the Bucks should be the ones to go after Pek. They have a great young core and the injection of an established post scorer may push them into the playoffs and help speed the development of Parker/Giannis. If they can build a trade around some combination of Ilyasova, Mayo or Sanders, their willingness to take Martin and a first I could see it happening. They could do Sanders + Filler+ first for Pek and Martin then Minn would just likely have to get a 3rd team involved for Sanders (they would likely need a PF). Maybe involve the Cs and do this deal
http://espn.go.com/nba/tradeMachine?tradeId=mebfrpoMin would also gets protected 1sts from Cs and Buck
The Bucks
Pek, Henson, Parker Martin and Knight would be a nice mix of youth + vets in the starting lineup.
The T-Wolves
Assuming they lose love and get Wiggins and Bennet. That would give them
Dieng, Bass, Green, Wiggins and Rubio. At least its an athletic group for Rubio to run. Gaining two first would set this team up for a rebuild while not going into a full on tank.
The Cs
Get a rim protector in Sanders and clear up some roster redundancy. The roster will be painfully lacking in shooters but should play great D.
