63 Dart, GT conversion?

That B frame "pillar" is also where the rear window slides up and down. It is riveted or spot welded in place. Im wondering if that can be removed and use the doors with glass and rear windows off the 65 GT.
Never say never. With enough know how and enough beer you can do it I am sure. Heck the B body guys have been changing 4 door cars to 2 door post cars for years. You just have to get it done.
