Aurelion Sol spell rework ? good or bad idea ?

Ok I'm not a developer but I had an idea. I really like this champ but I think he's weird. Not bad, just weird. So I thought of how I'd like to see him. The more I think about it, the more I think it's a good idea:

P : Because you can't be hidden in the bushes, then no one will. When a star touches a bush, the bush becomes "ignited" for three seconds dealing few damages to the enemies inside. They're not revealed.

Q : A little roar that knock back enemies in a line (like the actual R) with a cooldown like 6 seconds

W : Still the same thing but with a tap/hold ability and five ranks with the level 1 offered at the beginning TAP : extend the reach HOLD : slow down Aurelion Sol while it speeds up the stars

E : Still the same but you can hold the W to land brutally, dealing damages in the area while going down

R : A bigger version af the actual Q spell but doesn't stack with the distance and interact with the other spells. Q : pushes the vortex away in the direction of the spell, ending the loading W : the vortex "eats" the stars passing throw increasing its size and damages E : the vortex can be casts while flying following Aurelion Sol like the actual Q R : Tap agin to make the vortex exloses

Advantages :

• It makes more sense to have an ult that creates a star while the Q spell is just a roar.
• It can give Aurelion Sol a second spot as a support that can knock back or poke or stun the enemy team.
• Roaring more often can make him better against melee champs while forcing him to master the W expanse to poke as a midlaner.
• Landing brutally can give the E a more useful place in his kit

Thank you for reading and please tell me what you think about it. Also I'd like to have the opinion of someone from Riot to explain me how my idea is good or bad and why.
