Can we get a buff to Nashor's Tooth to increase build variety

I'm not just plainly asking for a buff here, I'm asking for variety increasing changes. So other things could be buffed/nerfed/altered to go with this, and I would be happy with it all.

I want to see an increase in build variety, which requires an increase in viable builds. To purposely use what some might consider an extreme(ish) example:

Ashe, a full fledged adc, has some AP scaling on her ult. This does not matter in the slightest. Riot put it there so they could point to it as an example of available variety, but it's not actually available. If you ever try to play as AP Ashe, you're going to have 4 leavers on your team. Leaving matches like that is never ok, but the fact stands that they had a reason to do it, because as it is you would essentially be trolling the F out of them by wanted to play AP Ashe.

I would love to see Nashor's Tooth buffed to a level where you actually could do things like AP Ashe without being considered a troll. I want nonstandard things like this to be sufficiently viable to actually be usable, for the sake of variety. No, I of course am not saying an AP Ashe with Nashor's should be dealing as much basic attack damage as an AD Ashe. If it was equal variety wouldn't be increasing in the context of her, because then people would only play AP. She should be dealing less basic attack damage than her AD equivalent, but still be dealing enough that when her whole kit is looked at (i.e. worse basics but better ult) she's still viable. Different, but still viable. Is your team lacking AP? Then take AP Ashe. Is your team lacking AD? Then take AD Ashe. You're one of the other roles and your carry says they want to AP Ashe? Then you know the team is getting more AP from bot lane and you can open up your choices in your role. Doing this could increase build variety not just for the champions building the Tooth, but also for the rest of the team as the team forms a comp.

Ashe was just an example, there's a fair amount of ad champions who have ap scaling somewhere in their kit that they don't actually have. I would like to be able to use it, to increase build variety.
