Wit's End + Sated Devourer

I feel that Wit's End can now be viable on champions that want to go for Sated Devourer, as this combo gives 104 on hit magic damage that gets stronger and stronger the more you hit the enemy. Sated Devourer's passive also lets you do this on hit damage twice and stacks Wit's End faster. Champions that I think benefit from this are Warwick (obviously), phoenix Udyr (still obviously) and Jax. What is the general opinion on this?
