In the Odyssey universe, I wouldn't imagine Illaoi as a captain of a crew, but as a priestress of Ora, like Sona was. Someone who has sworn to protect the Ora from everyone who wants to abuse it, like Kayn wanted to.
Her idol could be something holding an orb of Ora, too. And her tentacles are created by Ora, but she uses this power just to protect it, not for her own benefit.
When it comes to a crew, these would be my personal wishlist:
Odyssey Camille
She should be the captain, imo. She is just perfect, she is experienced, she is calculated. She even has an augmented body, which makes her work so god damn well with a scifi thematic like Odyssey.
Odyssey Blitzcrank
Scifi skin line and I think having a battle and labor robot makes alot of sense for a crew of space pirates.
Odyssey Viktor
The guy who has built Blitzcrank, the techy of the crew. Camille's old friend, maybe he was even the one augmenting her in this skin line.
Odyssey Twitch
The skin line is basically a hommage to Guardians of the Galaxy. I want Twitch referencing rocket! He fits well, he is a crazy dude who just wants to blow stuff up. Maybe he is a criminal the crew has caught, now because he can prove useful for their mission to save the Ora, they set him free to wreak havoc.
And last, but not least, the big villain of the next iteration of Odyssey:
Odyssey Urgot
Ora energy fueled shotgunknees! A final battle with drills you have to dodge to not get executed by him in his Ora generator!
Urgot deserves to be the major villain of a skin line.
