Any chance of a "Warden" playlist for a weekend?

I keep wanting to have a chance at being the size of Warden Eternal and just wreaking havoc on AI and players alike.
How difficult would it be to throw in a playlist where it picks 1 of 4 at random and give that person size,power and shield buffs?

1 vs 3
4 rounds - 5 minutes each - killing a warden does not end the round
Players have normal starting weapons and access to power ups on map
Warden uses warden type weapons.

Id also throw a “player warden vs AI only” in as well if it were up to me because sometimes real people quit or DC.
