If your out of warranty, I think it's a great idea. I'd start by getting a build print from Jayco for the curbside wall, roof and back wall.
You're on the right track thinking small - and if it were me - I would consider the alternatives of a small skylight or back facing window, too.
Good luck and keep us posted if you move on it.
