Well, some bikes lend themselves to it better than others. A cb1000 isn't a whole lot larger than a cb750. Also, a cafe racer is meant to be compact and so may not be comfortable to you.
You can use most any bike for it, some will just need more work than others. As to the original question, no, I have not seen 1 based on those chassis.
The ride IS the adventure. The destination is just to get gas!
