A Different Lore Idea for a Zilean VGU

Howdy fellas, I consider myself a big fan of lore and reworks (League lore especially,) and I recently thought of this idea for the inevitable Zilean VGU. I look forward to reading ur comments down below! =)

To start off, right now we have two Time based champs, Ekko and Zil. Right now, Ekko is obviously the more fleshed out, 3-Dimensional character, with Ekko taking on a gifted, scruffy tough boy living on the tough streets, with different aspects of hextech/steampunk aesthetics. He's a spunky, adolescent child, and hasn't really dealt with coming-of-life issues until he lost his friend by the hands of a foe. Ekko has a really amazing/underrated character design, and definitely fleshed out and relatable.

Now, what if Zilean was the polar opposite?

Now, I don't know if Riot would ever go into the direction of Ekko and Zilean ever actually interacting, but I feel that since Ekko is just learning and going through the issues of adolescence, Zilean should be the one who's been through life's problems for decades. He should be the patient, mild-mannered counterpart of Ekko. I think a subtle yet direct contrast would make an interesting dynamic, but I also think Zilean should have different aspects of time than Ekko. For instance, Ekko should have more direct sources of time travel, such as going back in forth in the same time dimension, while zilean can go and back from different time zone/dimensions. Also, Ekko and Zilean could have a Marty McFly and Doc Brown inspired relationship like from Back to the Future. I know that could be pretty hard to understand, but for instance, Zilean could be originally from a Runeterra that's been through the cataclysm of the runes Ryze warned of, but was lucky enough to time travel to this world to prevent it from happening here, but he should have NO relationships to the void. I feel his allies would be:

They can meet up by some chance, and since they share the same goals, cooperate somehow

When time travelling through different space time continuums, he could have a cosmic epilepsy, and could greet him to Bard

Wandering for help, he gets rejected from Piltover for his ludicrous ideas, and looks through Zaun, and Discover Ekko, and they develop a mentorship kind of friendship, and grow attached (Doubt though that Riot would allow Zil and Ekko to meet tho =( Who knows tho )

Don't know who rivals would be, so if u have any ideas for them, please let me know ! I doubt Riot would actually consider this, but I think they would like some sort of ideas from their community! I'm psyched for the future brings, so if you guys have any ideas or notes you would like to share, go for it! Thanks for reading! =)
