[Star Wars] What if Palpatine didn't punish Vader for failure and got the absolute best tech for rebuilding Vader?

We already have an example of what the best cyborg tech available to the Sith was - General Grievous. 

A top form Vader would be a mix between the Vader that we see and Grievous.  Four arms, claw feet, unmatchable strength and speed, a cool cape... 

But unlike Grievous, Vader would also be an incredibly powerful force user.  

If Palpatine gave him a Grievous body, Vader would have probably successfully killed him long ago.
