Hextech Crafting Improvement Suggestion

As a veteran player of 6 years, there was one thing that I noticed that immediately made me sad. As one of the many that owns every single champions through IP farming, the fact that we can't use Champion Essence completely trumps our stump. So here's a suggestion as per member of the community, how about we be able to convert say 100:1 of the Essences to another? 100 Champion Essences to 1 Skin essence, and 1 skin essence to 100 champion essence. This would helps individual who owns everything or whatsoever unlock few shards they owns but aren't able because they're short essences and have many leftovers on the other.

Thoughts?
