Question Atari 7800 Portable?

[Gabe8273]

Hey all, I am brainstorming a portabilized atari 7800 and was wondering if there are any resources for board trims. I couldn't find really anything but maybe someone here knows? I am kinda thinking like a horizontal portable with a d pad and a paddle under it (so you can also play pole position and breakout!) on the left, the two normal buttons on the right, and then all the console buttons lined up neatly on the top. Will make a rough model later.
