Occasionally I'll tie off with a mule knot and overhand, slip over the edge until hanging, and then release it to then rap.
Reading the linked canyoneering forum, some are suggesting taboggan'ing down as in sit on your butt or hip and slide on rappel. For raps on a wet & polished slot canyon, that doesn't sound too bad in terms of stability.
