What you describe is what we used to do with GT/TA cars way back in the dark ages, Ron.

The only concern is that with a modern unibody, you are actually gaining an important amount of chassis rigidity with glued-in windows - and not just the windshield. They turn those bays essentially into monocoque structures.

Given how cheaply we can get a mobile glass guy out to replace a windshield, I think gluing them in is a good idea.
