What you could do is play with the regulator and window and not roll up the window all the way to simulate the chop, then tilt the side window glass back in the regulator to match the new roof taper. if you find something that works with the side windows and still rolls up and down, then chop the door frame to match the window rolled up. Then chop the roof to match the chopped doors.

If you chop the roof per your mockup first, you would be stuck using lexan side windows and would be lucky to get one to roll up and down.

You can lay the windshield posts and windshield back but would only be worth a few tenths of sq. foot of frontal area reduction, but would be a ton of work. In a typical roof chop, the roof needs to get wider at the top or the side window slope has to change. They usually put in a filler piece strip in the center of the roof to make it wider.
