corrupted endermen (1.21)

so I was thinking to myself and I thought Maybe there could be a corrupted version of a enderman that was hostile to players and would be a boss mob that would be summoned when a player makes a T shape (like the wither) out of end stone and would put 3 jack-o-lanterns (not carved pumpkins) on top. it would drop a "ender star" that would craft into a "mega pearl" I hope you like my idea!
