Blue Essence Crafting Use?

So basically just wondering if there will Riot plans to implement another use for blue essence in crafting, owning every champion and getting champions gets pretty frustrating, but if you could turn them into blue essence and use that for something else or even convert it to IP I think it would be useful as I know a fair few people own most champs already. Comment any ideas you think would be useful to be able to spend blue essence on and hopefully rito notice.
