Inspired Champ Ideas

I was talking to some friends and we came up with a few good champs inspired from things people would know Anyone else have some good ideas?

My favorite of ours was another undead but this time a female (yorick is all alone) that has a spit or vomit projectile that lands like singed's glue as a Q, The W would be a shriek that buffs movement speed and spell vamp for a short duration called "need brains" The E would be a Bite that hits and marks them for a short while. The R could either be "undead" that takes time off your revive counter scaled with AP. The Passive would be infection which hitting them with any ability your next basic attack applies infection if hit with any ability after it the enemy is infected. As for the look we were thinking a mix between oriana and yorrick.
