Great idea. You might want to check around in your local area and find out if there are any machining or fab shops that do Lexan thermoforming. One of the great properties of Lexan is it's easy to form and the equipment to do it isn't all that expensive for a fab shop. You might get lucky. That way you wouldn't have the windshield constanly under stress which might lead to problems eventually.
