As for fuel savings, Nissan already has a ton of cars that are economical. They can make the Z as efficient as it can be for a sports car and call it a day.
Also, if you are concerned about price there is a very easy solution:
4 banger entry model with no frills for cheap
NA 6 sport model for more money
Nismo Turbo model for even more money
It's not rocket science. America has done this for years with the Mustang and Camaro.

You are all over the place.
You're not considering the business aspect of it at all. They can't (or won't) afford to make an engine specifically for this car, much less three of them. They've already committed to a V6 twin turbo motor that will likely get dropped into the Q50 and is confirmed in the Q60. That motor will not be lighter than the VQ37, but if it is, it will not be by much. Think about it - should Nissan use THREE different engines, you have a platform design challenge already. That means the lowest common denominator for design has to accommodate the largest engine. How are you going to downsize the chassis? You're not. Go look at the engine bay of an Infiniti M56 and compare it to an Infiniti M37. That car is almost a foot longer in the nose so it can accommodate a 5.6L V8.
Your master plan of three engine models to take care of pricing is totally hosed. A turbo 4 Z (which will be needed to move the weight of the platform that will have to hold an NA 6 and turbo 6) will be no less than $25k. Which means a regular V6 will be at the same price as the current 370, and a twin turbo nismo model will be in the $50k range, guaranteed. Guess what's going to happen with that? The top model will hardly sell and be discontinued. The midrange model won't be terribly competitive. The bottom model will depend solely on the health of the market at the BRZ and Miata level, which isn't looking good for anything except the Miata.
Fuel efficiency and emissions is a completely different argument. You can't draw a straight line between the two.
Finally - when in the blue **** have the Camaro or Mustang ever lost weight while gaining power?
