Mecha Rengar Ultimate suggestion

I saw the upcoming pre-release for Mecha Rengar, and it looks really well done! Don't particularly main rengar, however I did have one suggestion for the skin. Wouldn't it be better if Rengar transformers into a car whenever he uses his ultimate? Just like Mecha Zero Sion, I think that would bring a better incentive to get Mecha Rengar. Then right when he pounces on someone, he can transform back into regular mode and continue on. In my opinion that would be a much better change, before it goes out into regular League. He transforms into a car during his backing animation, but I thought it would be cooler driving around in the jungle hunting for a low enemy than just running in a metal suit.
