Is it too much to ask for Kha'Zix's Isolation radius to be reduced?

I'm not asking for 350 again, an honest 400 would probably be the best length for "I can tell i'm actually isolated" to "Kha'Zix now has his one moment less restrictive" ratio.

Not only that, but since the isolation changes, he could no longer pull the red buff into the bush for isolation, which hurt his clear pretty hard (and fast/healthy jungle clears are a huge part of viability in the jungle.) If he was able to isolate red buff again, I think it would help his first clear immensely, while also letting you forgo W buffs which will discourage the W max/evo poke'zix that you guys seem to not like very much.

if you can't make isolation available through pulling red buff without breaking the range again, could you make an exception for monsters to have smaller iso ranges?
