The new Conquerer skin for karma just came out and it got me thinking. That the skin would have been perfect for Syndra! In saying that she doesn't have that many good skins, she has one really nice skin (Snowday Syndra) And Two mediocre ones (Justicar Syndra and Atlantean Syndra)
So Vote what you reckon her next skin Should be. 
Star Guardian Syndra is quite probable right now, it was included in a leak with 2 confirmed reworks, 4 confirmed skins and 2 confirmed new champions.

I'd be willing to bet on that being a skin within the next few months.
I'm personally pretty happy about that since out of the skins you listed I think it's my second favourite idea, I've personally always wanted to see a Pool Party skin with either beach balls or volley balls, they just work too well. I'm fairly sure I'd pick up and use a Star Guardian skin though, it should be a fairly hard skin to fuck up IMO.
Project Sandra, and change her balls into different 3d shapes.
Infernal Syndra Soul Raven Syndra Death Soul Syndra Ghost Bride Syndra Victorious Syndra Lunar Wraith Syndra Popstar Syndra Arcade Syndra Ravenborn Syndra (from lb ravenborn skin) Pharaoh Syndra Bewitcher Syndra Dark Orb Syndra Dark Crystal Syndra
My ideas :) PRETTY BAD but oh well :D
Also heres my skin ideas for champs https://boards.na.leagueoflegends.com/en/c/skin-champion-concepts/7UW5V9sK-my-skin-ideas-2nd-part-poll
I'm surprised that no one mentioned the possibility of a Dark Star Syndra. Replace her levitating balls with galaxies. I mean cmon Riot. She's purple! That's like 50% of the work done for you guys, yeah?

Excuse your face.
Anyway, a skin where her abilities use black inky splash effects would be neat.
