Maybe try making your own from CF, you could use the shimano ones as a guide/template and use a small sealed bearing. If you could grab a small sheet of CF (*cough*ebay) and possibly a bearing from a hobby shop you would probably pay the same or less than a bought one anyway. I know hobby shops carry heaps of small cartridge bearings for R/C cars etc.
As for the cage mods, since you already have a sheet of CF, why not just make up a new back plate and make it even more fancy? I have seen a few people make their own back plate and they have threaded straight into the carbon with success, rather than trying to mount a nut or something to screw into with the jockey wheel bolts.
Good luck, and be sure to show us whatever you end up with.

I believe the idea was that you could use a shorter cage with a bigger variety of gears (like in a triple). You should still be able to find these replacement wheels if you want to give it a try but you would need to modify the inner cage a bit as well to make enough room for the pulleywheels.
