I think I finally found a setup that will work. Its not exactly the style I had in mind but I think it might do the trick.

Eagle Alloys series 146 comes in a 15x8 with a +27mm offset in 5x114.3 pattern. These will accept the 245/60/15 T/As I have been eyeing.

I did some measuring and given the difference in offset combined with the difference in 9in down to 8in width, the outer lip of the wheels should actually be about 1/4 in farther than it is now...so it should still have stout look.
here is the wheel

Now if the union and the company can just settle the labor contract I should be in business.
