Should there be more Champions who forcibly convert one stat into another?

Pyke's mechanic of not being able to gain bonus health and instead converting it into damage presents an interesting idea on how to curb assassin durability. It also presents a neat way to stop certain tanks from getting AD (i.e. from a Trinity Force), letting them convert it into either armor or magic resistance.

Should this sort of thing happen more often, or is Riot only planning for this to be a one-off?
