It's an interesting idea, but my sense of the situation in OKC is that Presti is not keen on trading youth for veterans...he's trying to build a team from the ground up with a solidified team culture.  To that end, he'll prefer to keep players that have come up in his system over trading for veterans toward the end of their careers.  This is exemplified in his recent extension of Nick Collison's contract (using the Thunder's cap space to do so).

While this trade would very likely make the Thunder better this year, I'm not sure it would make them better in the long run (unless Monroe really puts it all together).  While the Thunder are very good now, I think Presti is (quite rightly) focused on the long run, since his team is so young.

I've seen several Pistons games this year.

I have been impressed with Monroe so far. Nose for the ball, good passing, hustle on the offensive glass. He's a keeper.

Daye shows flashes of brilliance, with a good outside shot. The problem is determining what his true position is. At 6'11" he looks to be a stretch 4, but he is simply not strong enough to defend opposing PFs. He may have to play SF. He still has a bit of the deer-in-headlights look about him. Not even sure if he is starting material.

Prince and Hamilton are desperately in need of a trade out of town. Terrible body language. I suspect real animosity towards the head coach Keuster.

I think Dumars would prefer to build around the core of Stuckey, Gordon, Daye, Villanueva, Jerebko, and Monroe. Ben Wallace will retire as a Piston. The rest of the roster is trade bait or end of bench material.

Guys like Prince, Hamilton, and Maxiell will probably be mentioned in rumors leading up to the trade deadline.

One last note: I've been really surprised by Tracy McGrady's relevance/effectiveness, especially in helping run the Pistons' bench offense. I think he could actually contribute to a contending team in limited minutes, provided his knee holds up. The training staff in Detroit are top-notch.
