Pre-Battle General Grievous and new visual update

Karfax

When the screen is black pre-battle with General Grievous we can currently hear all 4 of his lightsabers being ignited and one would assume (and hope) that his 2 arms divided into the 4 arms we know of.

With the hopeful faction pass of the Separatists and General Grievous Could I offer some visual Ideas on his rework? which we all know is overdue.
As he has been and may still be the longest and hardest character to acquire (less Commander Luke) could we make him feel a bit more epic for who he actually is?

1) Make him larger, I know he's bent over in the game but in the films, he's rather tall (7/8 foot).
2) His pre-battle visuals: Could we see his arms divide and take his cloak off perhaps?
3) As well has his Sinister Laugh ability could we also hear him cough intermittently like the film?
4) The burn and flame trail visuals to be more like Darth Sidious that he leaves behind.

Thank you!
He already looks good model wise, he just needs to be a bit bigger and more foreboding.
