Swaping window frames?

[CG]

So I know the basic doors on our trucks are all the same. Window frames are different.

Is it possible to remove the window frame and install a different one without hurting the paint on the outside of the door. Not worried about the frame, and not worried about the inside of the door. Only what you see on the outside.

Ive never pulled one off before. It looks to be welded on the inside, but not on the outside.


EDIT: Was just thinking about this. Would it be possible to just cut the corner and swap? Going from truck rounded to burb squared off
