Many years later, I've finally done the swap =)

The wheels/tires are:
Front: NA1 NSX rear wheels, 16x8JJ with Kumho Ecsta SPT 225/50V-16R
Rear: NA1 NSX front wheels, 15x6.5J with Kumho Ecsta ASX 205/60V-15R

I had to bore out the 'front wheels' (NSX rears) to 70.1mm. When I first fitted the tire-less rim onto the car I was worried that that wheel would be so wide it would bang on the suspension. It was a very tight fit but the wheels worked.

The front of the car has a much wider track than the rear now. I'll get pics up over the weekend but the +55 offset was barely enough to get the wheels just inside the wheel wells (tires/rim are now just out of line of sight from above). I can't imagine how much bigger the contact patch is up front but the wheels are a full inch bigger in diameter and 1.5 inches wider too.

I chose the factory KA7 Legend tire size for the 'rear wheels' instead of the NA1 NSX factory size to reduce the diameter differential between front/rear with staggered wheels. I was worried that it would be clearly obvious that the front wheels were larger than the rear wheels but so far no one has noticed (must be some kinda illusion since the front wheel wells are so much bigger anyways).

I haven't had a chance to really push the handling yet but the car has a pretty strong tendency to oversteer (as expected). The rear wants to pull out but any jab at the accelerator brings it back in line. It seems quite unstable on the edge but that just might be tread squirm because the tires are new. I'll take the car up to the mountains this weekend for pictures and more testing =)
