A “unique” way to bring in the knights of ren

Ok so the title might be a bit misleading 🤣

but I think this would be a cool concept, which could be used on more characters also,

but bring in at least 4 of the knights of ren, 

but then, instead of a leader ability, give regular Kylo (obv the knight of ren tag as well) a unique which states while Kylo is in the leader slot and all allies are KoR do (insert whatever the lead ability might be)

this way they can give him a leader ability, but can only be used for Knights of ren, and not interrupting the flow of current FO team leads
