Idea for Mecha Rengar

I have an idea that would make Mecha Rengar a much better skin. Since Project Vayne and Pulsefire Caitlyn get to ride on motorcycles at high speeds, why not let Mecha Rengar transform into a car? Or at least for his ult, he transforms into a car while turning invisible, and when jumping on somebody, jumps out of the transformation (similar to a transformer). It's a pretty cool idea don't you think?
