What would people think of a champion kit like this?

Been fiddling around with a champion concept and maybe I can get some ideas here.

It's not complete but how would a kit sound like this?

Melee champion

Passive - gains miniscule attack range per level, as well as a Nautilus-style auto attack passive but only a slow (so can slow once on auto attack but then has an internal cooldown where a target cannot be slowed again)

Q - Two casts: 1) Sweeps in a crescent in front of her (kind of like Diana's passive), whose radius scales off her attack range (so it would increase with her level), and applies on-hit and spell-hit effects. 2) Unleashes a Ezreal-ultimate projectile (not global ofc) which deals equal damage, but if a target has been hit by the first cast it only deals half damage.

W - Passive: has an on-hit effect of flat magic and physical damage. Active: Increases attack range by a significant amount to become ranged, and for this duration (will be short like around 4-5 seconds) all attacks deal percent-health damage in mixed damage (physical and magical).

E - Dashes to a location, dealing damage to all enemies on the way and at the location. can be cast a second time to apply double passive's slow to targets around her; if they are very close to her they are rooted instead.

R - Active: Summons light from the sky to knock enemies back around her. Gives a steroid of a percentage increase in offensive stats (AD, AP, Life Steal, Spell Vamp)...like 10-15% ish. Can activate again to grant a shield (won't be too durable).

She'll have both AP and AD scalings but the point is to emphasize her strengths in each. If she goes AP she'll have higher burst, if hybrid with attack speed she can shred tanks faster (due to mixed damage being harder to itemize against), and if she goes AD she'll have more sustain with crit, lifesteal, and stuff like that, or she can build tanky and try to rely on her steroids but her ultimate is percent-based and so she won't have a lot unless she specs into damage.
