Night floating/ motoring is the ticket to making this happen on such a tight schedule.
The only time I've done Cat, we launched from potash in the dark and motored into the wee hours, then literally went to sleep floating. We woke up eddies out against a cliff and I couldn't have told you which way was upstream until dawn. We motored the rest of the way to Spanish bottom and camped around the first few Rapids, X or Y canyon maybe. We spent two days, maybe two nights even, at this camp with a nice surf wave and spectacular beaches.
We ran all the rapids the following day , and motored I to the evening.
We again went to sleep drifting and woke up with just a few hours of motoring to reach the take out in the am.
That program would work, minus our stay over camp.
Be a small organized group, with easy meals to make on the boats.
Motor failure would render this impossible.
It's not the list relaxing way to run Cat, but if you don't have time and really want to run the canyon, it can sure be done.
Shuttle can be pre arranged to move cars from put in to take out.
Arrange it early and maybe even mail them the spare keys.
This is exactly how Randy would do it!
