I think it's a great idea !!!!
Back in the old days I HATED it when guys would see our Pontiacs at the races and want me to come over and look at their GTO or Firebird, which I would, only to get there & see a Chevy motor under the hood. I wouldn't even talk to 'em. Just turned around & walked away.
SO, just as a revenge factor, I LOVE the idea of putting Pontiac power in most any GM that came only with Chevy power. That's also why I love the 3rd & 4th gen drag cars that have real Pontiac power. I think they're cool !!!
I suppose that makes me an old school Pontiac freek. So be it. I wear the label with pride !
