PERP died two times now and that was one server altogether.
But the concept is fairly simple so I don't see how it couldn't work with a bit of coding.
The idea is in fairness a good one and like how you've approach this but:
All concepts are fairly simple to begin with, but you need resources for it.
Good luck with the suggestion!
PERP is a gamemode in which a great level of depth must be achieved.
Prop Hunt and Hide and Seek do not have to have a great level of depth, and only a few modifications have to be made instead of the big overhaul that PERP has to undergo.
