What other champions would you all like to see in the Steel Valkyries line?

Note: The Steel Valkyries line consists of Dreadnova Gangplank, Dreadnova Darius, Bullet Angel Kai'Sa, and Gun Goddess Miss Fortune, according to this.

I thought the whole futuristic galactic setting was really goddamn cool, and I'd love more champions to get skins in this line.

However, the only champion that I can think of at the moment who would fit nicely in this line would be Quinn, since Valor could be this wierd robot-bird-thing that would be a part of her suit. I'm drawing blanks trying to think of others.

I was wondering if you guys had any more ideas for any possible champions that might have a skin in this line, since this is one of Riot's cooler skin lines and it has a lot of potential. A Rioter might also let us know about the future of the line and where they plan to take it from here, if we're lucky enough that one responds to this thread.

Anyway, go ahead and discuss about your thoughts for any possible skins we could get for this line.
