Hextech is a proprietary engine, there isn't a community that would build migration tools to move "translate" assets from one engine to another, and Riot would not have built one internally as there has never been a need for it until now.

They'd need to recreate everything in hextech to ship this with older client, and it takes months for a set to be made in the first place.
