removable/opening rear side windows

just brainstorming a bit here...
How cool would removable side windows in coupes be? I think it would be freakin sweet. even if they just opened. not like roll downs but open like EF hatch windows. my buddy had an EF hatch and we used to undo the 3 or 4 screws on the hinges and take the windows out completely and stash them in the back of the car.
I can't see it being super super difficult but I know there would be sealing/leaking problems... I was thinking something along the lines of taking the windows out and fitting in the place of the silicone then fitting something on the ends of the windows with bolts fixed that go through the gasket to the inside of the car so you can put wing nuts on them so they can easily be taken out
again just brainstorming here. any input
