Your idea would have been a good solution a year ago… but sadly their is no way to implement this right now.
The lowest level player in my alliance is sitting at 600 trophies and has a level 13 sino… 14 eino and a few level 7s. What bracket would he fit in?
My next lowest player is at 1200 trophies and has a level 17 sino and 15 rex.
I have someone at 1600 trophies that has a level 18 eino. I have multiple people that have indom and arent even at 2k trophies yet thanks to daily missions of rex for a month.
