What if lulu was reworked with the idea of hugify as a theme?

I got to thinking... making things bigger could be a LOT of fun. so... heres an idea!

Passive: Hugify! Lulu can target allies with basic attacks. Lulus basic attacks add one stage of growth for 5 seconds to allies and recover 1-2.8% of their missing health based on level. Growth: Increases unit size by 10% per stack, maxing out at 100%. At 100% growth on allied minions growth becomes permanent and does not stack any higher.

Q: unchanged

W: Pix Passive: Pix adds 0/1/2/3/4 additional stages of growth. Active: Lulu sends pix to a nearby ally, shielding them from one champion ability or critical strike and healing them for 5/7/9/11/13%+10% per 100AP of their missing health. Cost: 50 mana Cooldown: 10 seconds

E: Greater Hugify! Lulu targets an ally and adds 2/4/6/8/10 stacks of greater growth for 3/4/5/6/7 seconds and increases their size by 10/15/20/25/30%. Each stack of growth and greater growth adds an additional 1/2/3/4/5 AD (up to 10/30/50/70/90). Cost: 80/85/90/95/100 mana Cooldown: 15 seconds

R: Whimsy Lulu grants herself and all allies effected by Hugify! 10/20/30% increased movement speed for 5 seconds and a shield for 100/150/200+10 per stack of growth+0.5AP for 3 seconds. While whimsy is active Lulus basic attacks gain 1/2/3 additional projectiles that target allied champions.
