It's my personal idea. I'm kinda obsessed with it because I haven't found anything similar on the entire web.
I scrolled itch with tag Adult down to the hole and haven't noticed a single one that uses real people representation. That's what I'm doubt about. It leads me to think that this is prohibited for some reason.
EDIT:
I'm actually found a couple games with embedded video content. Much deeper than I expected but it looks like my idea might have a greenlight.
