How would you feel about a scaling hybrid item?

Grants ap, ad, hp, cdr, and both types of flat penetration AND UNIQUE passive: You gain AP equal to (percentage) of your bonus AD and bonus AD equal to (percentage) of your AP. This passive does not stack with itself.
Often times hybrid items need to be hilariously overloaded with stats in order to try to make them attractive (see: Rageblade). This silly thing would allow hybrid builds to snag whatever they need from both sides of the spectrum without falling off too hard.
Thoughts?
