Possible ideas for new champs?

Hey guys! [slayer-jinx-catface]

So I've been going around and around trying to think of different ideas for new champs. Out of all the ideas I've had, two stick out to me the most. Let's go back to the idea of lore.

You know how Sivir's weapon was originally wielded by an Ascended Queen of Shurima? What if Riot actually brought her in as a champ? They brought Azir, right? He was an ascended as well, same as Renekton and Nasus? Well why not Setaka? She could be trying to take her weapon back or some other such thing.

Now onto my other idea. Senna, you know, Lucian's wife, the one that got sucked into Thresh's lantern? Well, here is a thought. What if she came back? What if something happened and Thresh's lantern cracked or something like that, and Senna's soul was released. But here's the kicker. What if she was now corrupted? Being in Thresh's lantern for so long had to have screwed with her soul. So now she wants nothing more than to destroy her once beloved husband, because he failed to save her. Of course, she can't have the same gun she used to have since Lucian has it now, but when you're a corrupted soul intent on destroying your husband, who needs a gun? She probably could have other weapons. Or she could kinda be like Kalista in a way? I dunno.

These were just a few of my ideas for new champs. Hopefully Riot can take a look at this. I've been rolling these around in my head for months [slayer-jinx-wink]
