Most would question installing anything but a Chevy engine in a Chevy car. I don't see a lot of questioning about installing a Ford 9" , or replacing a 10 bolt with a 12 bolt in a Chevy car, or installing Chevy engines in Ford roadsters or Chevy engines in 70's Pontiacs. It's a matter of choice. I know that it will detract from the value of the car, however if I ever need to sell it's easy enough to buy a low cost crate motor, do a swap and sell the Pontiac motor to Pontiac enthusiasts.

I like the idea of a Pontiac motor in the Acadian. It definitely will not be a belly button install. Aside from motor mounts to be fabbed everything else should not be a hard pull. Both are rear sump motors so cross members won't be an issue and there are TH350 and TH400 trannies available for both applications.
Go for the swap. Like you said you can always put a cheap Chevy in it later.
