Offensively, Bosh and Pekovic work. Defensively, though, I think it's a very weak combo. Bosh is, as Shaq said, the "Ru Paul of big men". He's soft. Like, Downy fabric softener soft. Pekovic isn't a good defender, either. He's great at giving hard fouls -- something he does a lot -- but he's not all that good in terms of the fundamentals.
This is the Roy Hobbs I know and love. If hyperbole were food, you'd be able to feed Africa.
Chris Bosh is not 'soft'. He not KG with his intensity, and he's not Kenyon Martin with his sheer brutishness, but he's not soft. Not with how he played in the playoffs through pain, hustling for boards, giving up the body, Bosh can't be called soft anymore than Pau Gasol can. Unless you want to rate everyone on old reputations, cuz if that's the case I've got some terrible news for you about Lebron.
As far a Pekovic, he does not foul a lot. This is not a supportable claim. He used to, Hollinger said he did in his player blurb in 2011, but he seems to have solved that particular issue somewhere along the way to being a 17 and 10 guy.
And for those of you uninitiated, Roy dropped a 'Complisult', which I followed up on with playoffs level snark. It how the CB Draft rolls
