Cy - It is a really big gamble to attempt to reveg plants after they are deep into flowering(very low success rate.) If there is no way for you to come up with some clones from another grower my advice would be to give yourself the most chances at success as possible.
It sounds like you really want to keep your cycle uninterupted and that seems difficult but possible. Take cuttings from all your plants in flower and root them. Don't worry about losing yeild this time around. Take enough clones to ensure a mother for future grows and your next grow cycle. Take enough to allow for some failure in rooting and make sure you focus on giving the clones everything they need. All goes well you will have this strain on the shelf as long as you want it.
Too bad you weren't up in the central valley I could probably get some cuts for a fellow grower. This is a nice experiment to try out.

Good Luck, Keep us informed. -Jay
