Nothing of that sort exists. Sorry.
You might be able to make a group booking with German Federal Railway but that would be for Koln - Basel and would be seats on a regular train such as an ICE, but they don't go the scenic route. You could also book a Rhine river cruise Koln - Basel but that takes a few days.
