Champs that I feel would have great project skins

Don't get me wrong, I LOVE the look of the project skins, I just think that there were/are better and more creative choices that they could have used.

These all would have been really good project skins. I mean, why doesn't Sion have a project skin? An entire seires of skin whose lore surrounds upon once dead soldiers being resurrected and Sion doesn't get one? For that matter neither does Azir (his solideirs could be holograms)
