Valkorion plus team vs PT heavyweights .

Setup:

valkorion replaces sidious and tries to seize power .
This time the very best warriors from the order are send to deal with him
RoTS yoda , RoTS mace (amped if need be) and zonakin go after him :
they also convince RoTS dooku to redeem himself and join forces with the jedi once again ,
dooku agrees and he receives a vjun like boost after his redemption .

This 4 jedi masters enter valkorions (sidiouses) senate office
(the same in which yoda confornted him) .
Anticipating this move from the jedi order
valkorion has help in form of vaylin and prime arcann .

All out fight .

either mace or dooku would be really tough fight. together they beat him for sure. yoda as well. zonakin gives him mega hell. together they stomp him

Valk solostomps them all. Granted, I hold Valk between ROTJ and DE Sidious, but still.

Valkorion in an immensely difficult fight. Honestly, the four of them combined would be around DE Sidious level, but he can conceivably pick them off one by one.

I side with the PT team. They wins solidly, albeit not easily. The presence of 4 Yoda/Sidious level combatants and one who is quite close to them (with the amp obviously) is too much for the other team to handle.

Team Valkorion.
