Aurelion Sol Rework?

This is simply an idea for an aurelion sol rework. i'll be completely honest he is manageable as a champion but the same time also underrated in the sense that, his moves do nothing effectively. you play him and you'll understand.

Passive: Comet of Legend, (theres a reason for this insanity) im thinking this ability essentially stays the same via the speedboost. but on activation (like Kayne?) you have the ability to fly. how you activate it is via Taks, you get taks by killing 25 Minions, Killing 3 Jungle Cams, Killing 1 Enemy Champion. when you have 3 your able to fly.

Q: It can stay the same since its really good, though instant activation would be nice but whatever.

W: Combine Celestial Expansion/Center of the Universe. it is what it sounds like, though you will need to tweek it a bit to make it less op. PLUS gives you the early game option for bush ganks, pick Q and you wont have any orbiting stars.

E: Make this the Voice of Light Ability with Decreased DMG. so this one im going back and forth on. mainly because im thinking about keeping it as an Ult, or Replacing it and making it a weaker E escape ability.

R: the reason people have an issue with Aurelion is basically anyone can enter you circle and kill you. i was thinking of making the ult like this. Celestial Expansion Actives while also giving you a inner ring of stars (aka 6) outer ring moves slower but adds a slow affect. the inner ring deals increased DMG while withing the circle is Celestial Flames, which if you can guess is like the Cape of Flames item? lol bad memory but yeah, this eliminates that advantage if you can activate it while they are close n keep others away via the slow affect.

this is my idea for a rework but hey im no expert, is this a good idea or not? you decide. and have fun lol.
