I actually really like those types of changes to Executioner's Calling. MS-proc, Health, AD, Crit % and Griveous Wounds would be really unique, I don't think there is anything else quite like it in the game. I've spent a few minutes and I can't think of a good flavor reason it wouldn't make sense.

I think the next question asked is if that fills an item niche? Does something else already sit in that niche; if so does it need an alternative?

It would look to be a a counter-hyper sustain item (from a design standpoint I think could be dangerous, it could invalidate entire champions). Nothing else really fits that niche from an AD standpoint (considering it would be a rework of Executioner's).
