I personally would love to see -Annie (legendary) -Zoe -Nunu -Taliyah -Ekko
Or you can replace any of the above with, -Kai'sa -Talon -Kayn -Tristana -Sivir
Who do you want to see in the Season 3 of Star Guardian?
More Star Guardian skins, 'cause why not... :')
What leak? And of your lists, I only agree with Taliyah, Talon, and Sivir as potential candidates. Taliyah because she's been begged for for foever. Sivir because of moon tiara power. Talon because we need more anime boys. Though I take hella offense that Taric is nowhere on this list.
Why have new members when you can make skins for the skins instead?
My personal favourite candidates for the next Star Guardian team are:
Strict teacher that can get a bit frustrated with the younger guardians.
young recruit earnestly trying to learn. Gets roped in by Zoe a lot.
spas that has a lot more power than she ever worked for, and now is a bit mischievous with it.
This is the group I always put in these posts. I view Taric and Camille as the older guardians that now have a bunch of really young recruits to train (Zoe, Taliyah). The story has kinda built itself from the champions after a while haha.
Btw, do you think the star guardian universe is in the same one as the high school skin series? Not sure if I do either but it just kinda popped into my head
I’d love to see Xayah and Rakan, fiora, or karma
I want a reverse team where 4/5 are males and 1 girl.
Could very well be named Star Knights to differentiate, also cringy names like this happen all the times in mangas and such :P
My comp would be: 
I really hope they wouldn't waste a SG skin on Taliyah. And Ekko? Yikes. I see ppl saying Annie but i much rather Annie get the next ultimate skin...so no legendary for her via SG.
My picks:
Same as your first list, but replace Ekko with Sona and make Taliyah or Zoe the legendary.
I really love the "anti Star Guardian" skin ideas and I hope that it'll be true! Syndra turning evil is a really funny idea with Veigar as the evil overlord :D I don't think it is impossible, since we already got the pyjama star guardians and they announced the star guardians to come back this year!
I also love the idea of Orianna as a star guardian, she could look like Penny from RWBY~ Evelynn and Tristana would be cute too!
Would never happen, but imagine Star Guardian 
and his 4 little animal friends.
urgot 
(rainbow beams) 
stardust explosions
Vel'koz would be hilariously good
and zoe would actually make sense
legendary
