I think it would be an awesome motor, especially if they kept the HP north of 525-ish. It would be a good replacement for the fail-prone LS7 as a high HP N/A option.
Interesting to think about...

it's not that simple. they would have change the compression ratio, camshaft profiles, etc.
it would be a new motor. they would probably stick with hypereutectic pistons in a n/a motor as well as they have a more optimum thermal expansion coefficient and you don't need a forged piston in that power range at all.
you pull the blower off and lt4 and you probably just have a 400-425hp motor.
my ls7 lasted perfectly for 5 years but I was stock. I did inspect the valve train geometry based on the paranoia around the platform though.
