I if you know anyone with basic machining skills, you can adapt early 1000 Ahrar wheels with a few bushings and a little trimming on your rear brake bracket. That's what I have run on mine since 2008 or so, they are still round, albeit less cool looking than the 6-spokes.

I have an '06 and I'm doing the swap. As stated the rear is a direct swap. The front requires different axle spacers and additional 4mm spacers on the brake calipers. My 600F3 front wheel came with an axle but I don't see the need to swap the front axle. The 600F3 front axle is actually shorter, I don't think you should run a shorter axle unless your changing the triple clamps. I'm using the tapered spacer on the right side along with another spacer turned to .462 inches wide and a stock 600F3 spacer .590 inches wide on the left side. I've done my mock up and confirm brake operation but my wheels need powder coated and new bearing/seals.
I think Woodyee's bike already had them on - I don't recall anyone writing up about putting them on, although they are pretty sweet-looking, and they were available for a while at clearance-type prices, somewhere up in the PNW.
