First: are you having a problem with WiFi signal? I would start with your router rather than the Studio.
After reading your post I moved my Studio to a spot in the house that gets the worst signal (in a nook in the kitchen behind a concrette wall & the refrigerator) and was still able to get almost full-speed (Gigabit) downloads and uploads.
The concern with flipping the Studio IMHO would be cooling. That said, even under fairly heavy load (rendering 8 concurrent streams of 4K video) the top of the Studio gets warm. Not fry-an-egg-hot like the top of an i7 Mac Mini. But warm.
If I were planning to do this I would put something under it to keep it off the desktop so I wasn’t creating a hot spot where the device normally releases heat.
