I'm not a pro by any means but I don't think that is not a very good idea. It will probably take a few weeks to revert back to veg, and once you flower it again, your chances of ending up with a herm are great. Its best to grow the plants to maturity and put clones from each into flower to see what they end up as since they will be of the same genetics. Then you can cull the males and focus on the females, and clone them further if you would like. I think it will take less time for you to do that than it will to flower for two weeks and then try to reveg because of the recovery from the shock of starting to flower and then being forced back into 24 hours of light again takes a long time to recover from.

Oh, and for more information on how to clone, just use the search. I personally use Dip N Grow and have had somewhere around 80% success rooting in rockwool in an average of 8 days. Just cut, dip, and put in the rockwool. The key is to keep the atmosphere humid by using a dome and then opening the dome to refresh the air once a day, and don't get the rockwool too wet or the end of the cutting will rot rather than root. Good luck!
