Guinsoos/Runaans balance changes

I propose a buff to Runaan's that would allow more Adcs than Kog'Maw to take Guinsoo's to battle. There are two phases, the first being a minor buff and the second being a much larger buff.

So the first buff would be, make it so that Runaan's bolts can proc Guinsoo's stacks. (Hit 3 targets with one auto, get 3 stacks of Guinsoo's) It would work like Caitlyn, Corki, Jinx, Lucian, etc passives already do when it comes to stacking with Runaan's bolts.

Now the second buff would be much larger, where Runaan's bolts actually proc Guinsoo's rage, that is to say 3 AOE splash damages of Guinsoo's on hit at 8 stacks assuming three targets are hit. This would make Jinx, who already turns Runaan's bolts into 2 extra rockets, into a monster, as with Kog'Maw, but besides that it would just be incentive for Adcs who buy Runaan's now to incorporate Guinsoo's into their kit.

Either/Or of these would make Guinsoo's suddenly viable on half the Adcs in the game, rather than just Kog'Maw.

As a side note, making the Fervor Of Battle mastery proc on Runaan's stacks would also buff the item and give further incentive to use the item/mastery on Adcs respectively.

Thoughts/Discussion/Feedback appreciated, let me know how I can make this idea better.
