New game modes?

I've thought of this, I thought for legion, have all 4 but under a rule, whoever is given Frank is just standard, the other 3 can only attack when undetected, if looked at for a few seconds, they disappear and placed in a random location that's far away from any survivor, they can crouch and hide and lunge out an attack, if successful in a hit that puts to injured, they disappear to random location, is in dying Frank can go over and then order his friend to move them, Frank can not move anyone and has to be there with another to order the move, there are 6 survivors (Frank can't move anyone) the other 3 move at the same speed as survivors, when Frank uses his power, all gain the ability except only Frank can vault the others can not, and they can get the hit even when detected, but disappear still after the hit, on the gates, all 4 now normal and will be savagely trying to kill, only Frank can be at the gates and the rest are limited to where they can be with gates being only allowed near if in chase and only for whom they are chasing, if Frank camps gate the rest lose the boost they got and good luck getting anywhere then, it's a challenge mode, not made for ease or anything but enjoyment and challenge, it's a challenge for killers as they are all limited to what they can do and a challenge for survivors cause there are 4 people and the gates are deadly to do now, reason Frank is the main one is cause he is the main one, his friends don't want to kill but he ordered it, so they do very limited help, his friends are as brutal as him after a while so gates are brutal unless Frank camps cause he is still the main killer, so it's made to be as lore friendly as possible as well as a nice challenge
