Star-Guardian Draven (Twisted Fate, Talon)
Before you start thinking I'm asking for Draven in a dress, I'm not. (Currently) Obviously Sailor Moon is a huge influence and everyone's really into the design they came up with. Instead of doing the same thing again, why don't we pull from the same source and use Tuxedo Mask, instead of a SS. Obviously, from a thematic standpoint on League's end, Ezreal would fit the skin more, (Sparkles, relationship with Lux) but Draven fits the idea from Sailor Moon's side. Tuxedo Mask shows up, throws roses, (which somehow makes him win) and then leaves.
Q - Draven spins his Rose, (The animation may need to be tweaked so that he is spinning it with his index, middle and thumb.) W - Sparkles, little stars popping off of him. E - For visibility's sake, Draven throws a full bouquet. That way they won't blend together with his AA and confuse his enemy. R - He could still be throwing roses, but the animation would look strange if they were suddenly larger. Instead, he chucks a bright array of stars. (Or moons, depending on your preference.) Two large spinning Stars side-by-side. They have their points be upwards, and would not sparkle. Again, for visibility. In case Ezreal is on the same team so people don't mistake one ult for the other.
*Cons Draven's personality doesn't match the character Animations may need to be altered

Other potential champions who would fit this skin:
_Twisted Fate _ Different cards could be different coloured roses His ability to teleport could have some music (Ala SGLux's B) and would play out like how TM acts, reappearing when their's trouble and start throwing stuff.
*Cons He would not lane with Lux often. He talks about how his weapons are cards His personality doesn't match His Magnificent skin already looks similar
Talon W is multiple roses, his cape and model fit with the design relatively well. His ability to go invisible would also fit Tuxedo Mask's persona of appearing when he needs to.
*Cons He stabs people, which seems weird for TM. (I've heard the reboot has him fight more but, we all know that's not what we want) His personality doesn't match Animations would need changes (Unless were fine with just giving TM a knife arm)
These two may actually be a better pick for the skin, but the idea is that they'll be in lane together. ADC Talon isn't a popular pick, and while Twisted Fate as a marksman is nothing new, it's not very common.
That whole copy-right thing: Tuxedo Mask typically wears a top hat, but not always. Getting rid of that, and changing the design of the mask should be more than enough change. There was less done to differentiate Star-Guardian Lux after-all. (She was literally just an older Mini-Moon)
