I remember watching a reverse isekai anime 10 years ago.
It's about a demon lord that came from the fantasy world to the real world, and he started working in the McDonalds.
It's funny, have cool action, but it's really cliche.
The anime women ranged from cringe inducing waifu to badass knight lady waifu (?)
The MC lives with a handsome demon man (ikemen) that acts as his maid, and a cute demon gamer boy. [Probably Fujobait]
Back then I really enjoyed this crap, but nowadays I'd never bother watching it, I'm not big in harems anymore, heck right now I barely watch anime because of Isekai saturation.
Go for it OP, but I'm not sure that Isekai (reverse or not) will stand out in the sea of isekai that we have right now.
Good luck!
