An champion who can give mobility to other champions?

Yeah, we're right now in the mobility meta, yet immobile champions lost their chance to shine. They can be still played well, if they're in the right hands, yet they can't utilize their spells as mobility tools, like jumps, dashes, and blinks. But what if there would be an champion, who would have as an ability a spell, that throw ally champions in the direction they are facing?(somewhat like Ziggs mine, just a bit different) I had this idea since long, though I never designed a champion and probably feel awkward about it too..

I'd guess it could become out of hand, if the player who has the champion that can give mobility to other champions to an champion that has already mobility. Though it's again in the decision of the player, wich ally they help. Thresh has his lantern as mobility tool for allies, wich is pretty useful, and I think there should be more champion those!

EDIT; Kinda forgot that Kalista can the same thing.. Though only with her Souldbound ally
