My thoughts, in order to do an expedition type trip it would require an extra few days to do it right. possibly more time than some could spend. Maybe meet at the original camp for a weekend, etc. and then anybody wanting to go on they could go as a group. Everywhere you've mentioned, we have on our list. Being an old flatlander, I've been trying to build up our mountain pass experience, but still not sure how I would feel on some like Black Bear Pass. Some of those higher passes might still be closed in June, I have no real time knowledge of that, just what I've read.
All that said, we'll try to make whatever it is.
