A possible way to improve player commendations.

[Judge_Xero]

Sounds like commendation abuse. I don't like the idea at all. If all the good players are getting pooled together then there is less motivation for new players and players struggling with the game will never get matched with skilled players who can guide them.

The commendation system is fine how it is.

This is the single most important reason why OP's suggestion wouldn't work.
