Lulu mechanic idea

so hear me out, for a while now lulu has been the same character, does damage but is more focused on healing and shielding. she is always hitting the same style. but here is my idea. since lulus ult creates a huge knock up, heal and size change. why not let pix be able to get ulted. how this works is when lulu uses her E on an enemy pix will stand on them. lulu then can use an ult onto pix that will create the same knock up, but an aoe splash of damage. the concept is either lulu can save a team mate or insta someone. if she chooses to save someone then she will be like lulu as we know it, but if she decides to kill then lulu will become much more capable to be one shot herself. I believe this will make lulu a fearsome character worthy of being titled the whimsical psychopath.

the ult would be for dmg something like 120,140,200 + .54 ap
