Lexus already seems to be attempting this with the LS600. BMW tried this with its first 7 Series hybrid, but has since scaled it back to a six-cylinder with more modest number. However if looking at a 7 I can't imagine why you'd buy the hybrid for fuel economy when the diesel-powered 740Ld bests it in terms of fuel economy. Not sure what the 0-60 is on the hybrid, but the diesel does it in under 6 seconds including the added weight of the long wheelbase and AWD.
