Can I please Not get Champion Essence If i Own them all?

Kinda self explanatory, but if I own all the champions, I don't want to get useless champion essence that is literally just a place holder. the chance of me getting key/box/ new champ when they come out is 1/130 + all of the skins and ward skins combined. I don't want to be filling a placeholder that does nothing at all for me. At least make it so I can give the essence to someone else or form champions for them. Otherwise this is just a number sitting in my Hextech that is a waste. The other option would be to only have one kind of essence instead of 2.
