Here's a cool idea: Robot Shyvana.

We already have that skin I forget the name of, also her ult transform animation lasts literaly a millisecond

Super galaxy?

I think the op is thinking more along the lines of Megatron from Beast Wars (his dragon form).

I would love this and to add to this idea I'd love to see a Black Arachnia inspired skin for Elise and an Airazor inspired skin for Quinn.
