Half Life 2 has always been one of my favourite games, and the game mode has always been one of my favourites. I would really like to see this happen. PERP did work before but it was the developer who let it die.
If Xnator gets a prophunt server which no one really asked for, give this other highly popular game mode a chance.
I am sure Chute, EMP, Viking and a lot of others are familiar with the game mode and how fun it is due to the popularity and FP previously having a HL2:RP server.
