Champion ideas?

So I have been thinking of some unusual ideas for Champion concepts, particularly when it came to relations with existing champs...here are two of my biggest ideas I can definitively summarize:

-A troll drummer, who is a political opponent to , a musical rival to , and drinking buddies with and . A sort of war drummer who sought to rally kin and friend with a rousing warsong from his ancestral drums, presumably in defense against those like Trundle and Lissandra. I imagine him to be a sort of a music based Geomancer, sending out quakes and rock drops with the beat of his drums...and maybe make him an AD mage. An odd idea, I know, but we already have a troll tank top laner (I mean a literal troll and not or ) and a song based support.

-'s sister, the Lasher of Repentance. Sealed in the form of her dreaded whip that had flayed thousands of bodies to the bone, this Darkin was eventually sealed in the vaults found in the Blessed Isles (rather than Shurima, like Varus thought), where other dark, corruptive artifacts were stored...and where she met true suffering at the hands of Thresh.

It went to the point where she now knew what pain she afflicted upon the residents of Runeterra and actually began to feel remorse and sympathy, possibly for the first time in her life. Fast forward to the present, and she found freedom when she found a host that would help her escape Thresh and the turned Shadow Isles, but instead of consuming said host, like her brother and fellow darkin brethren, and Rhaast, she formed a perfect symbiosis with them.

Personally, I imagine the host to be some hapless victim who got stranded on the Isles for some reason and lost an arm along the way. So, the Darkin used her whip-form to attach to the stub and become a sort of weaponized, symbiotic prosthetic. And that's where the idea ends for her ^^; Maybe her/them into a sort of short-ranged fighter, using the Darkin whip to harass enemies and maybe flick 'em away to grapple onto them? Her ult would be a sort of street sweeper that damages and slows enemies when she sweeps her arm in a given direction a few times.

What are your thoughts on these ideas?
