As much as I like your ideas, I doubt there’s going to be any time where the developers have free time to dedicate into Purgatory - As it does not require any updates to make it ‘interesting’, and no one really wants to make it ‘interesting’.
I feel like the main focus right now should be towards working on the actual Gamemodes on Munchy, and I personally wouldn’t feel comfortable with having a cute developer dude sit for hours and even days making features for a gamemode that is meant to serve as ‘torture’ for players who were banned, and that isn’t very popular but is just a side hobby for the main gamemodes’ players.
