Just a (Maybe meta changing) Idea

I was thinking on how to give champions more diversity, and I thought: what if all current champions get two passives?

Pretty much just that, we get two passives and we get to choose between them pre-match like how we choose summoner spells, masteries, runes and wards.

I'd like to think that some passives would be chosen to help a champion be better at another role than the one they're currently only capable of, I think it would give more variety, I think people like variety? What do you guys think.
