I think you will find that the Spandex will stretch significantly when it inflates/deflates according to the air pressures being exerted on the fabric. My thinking comes from my 1985 Toyota Celica convertible top inflating at the top edge of my roof line when traveling at speed (anything over 40mph). The material my top is made from is black Cambrio cloth and is pretty thick along with support spars to keep it in place. My top will rise in the front about 3" when traveling at speed. Something to think about before you put a lot of effort in yer gap cover.

You could try some testing of the fabric by taping it down with some duct tape before you do all the fab work and do a few test runs.
