Ultimate Skin Theory: Elise

My (hopeful, hopeful) money is on Elise.

1. not counting her Ult, Elise has 6 abilities. Two Qs, two Ws, and two Es.
2. Rappel is like hiding. She's untargetable and effectively invisible
3. Riot doesn't count her as an assassin, but her kit is built like one
4. the S and J hints are for Spider and Jungle
5. she only has three skins: Classic, Victorious, and Death Blossom
6. "Fourth spell letter A" works for her "volAtile spiderling"

The only thing I can't get to fit is "541daw6s5d41a6s5d" Thoughts? Debunks?

Of course it could just be Shaco like everyone says. Or Exterminator Twitch is really an ultimate skin, and we've all been lied to.
