Ricta tried this concept in 03 or 04, they retailed for $40 which was $10 more than most wheels back then.

I see now. I've been told Spitfire did something similar in the past as well.
I was visualizing inner and outer as something completely different, shown in the attached image below. This might be physically impossible, or if it is possible, fail to be a durable wheel.
Note: starting to attempt to attach images on SLAP's server, even though the limit is 128kb. Imgur is going to start deleting images not tied to a registered account on there, which is a damn shame. -
