I wouldn't worry too much about, since he technically has a similar effect on his R on live, which I'm moving to his Q (he wouldn't make as much use of the active, though the item would still be good for initiations). There would also be a bit of reduced synergy due to him no longer benefiting from the item's mana. I agree that might cause a huge damage spike on him, though, so that's probably something to watch out for. It's worth noting that his primary source of damage deals true damage, though, and that he doesn't go too crazy at the start of fights unless he's low on health, so unlike a lot of other very bursty AD casters he wouldn't be able to apply those stacks as easily, not make full use of them immediately.
