Other than aesthetics, what is the purpose of staggered wheels with the same size tire? On my 245, I run 16x8 all the way around with 225/50r16. Now, if I recall my old sales days, for every 0.5" change in rim width from the tire manufacturer's measuring rim there is 0.2" of change in tire width. From a handling perspective, I would not recommend it as the tires would act differently- bulge on the front, stretched on the rear. That extra 1.0" of rim width is not going to gain 1.0" of tire section width.
Typically one runs staggered wheels to aid in a traction limited scenario- take a 911. It needs wider rims in the rear, but also needs wider tires. You will not change the tire's contact patch with rim width. Substitute, high horsepower whatever car for the 911, and more CONTACT patch is needed on the driven wheels- typically. Some of the newer vehicles are breaking this rule- some Audis and the new Mustang come to mind, but that has come from testing not speculation.
These are my thoughts, accumulated from several years experience, but you are certainly welcome to do what you wish. Seems you are asking for advice for the sake of argument rather than knowledge.
do it in a Hawaiian Punch theme.
