Just pure speculations and blah blah blah-ing here but on the subject about Ginn and Mandy being "temporarily" uploaded into Destiny's memory banks:
Option A) We know that the Asgard were very famous for their cloning techniques, and we now have all the knowledge of the Asgard on board the Odyssey. So would it be possible that, if Earth is able to make a connection to Destiny periodically for supplies, we could supply them with the equipment necessary to make blank copies? Or was their technology faulty since they had to keep cloning therefore suffering from the law of diminishing returns? But back to the original idea: would this be a viable solution? I mean, they would have to have Earth supply a sample of Mandy's DNA and find something of Ginn's still on board Destiny to get a sample that way they could clone and then do the transfer.
Option 2) The "Replicator" idea: We obviously know we have the technology and know how to create human form replicators in Atlantis, since Rodney made FRAN and then the Elizabeth used the same program to build a new body, etc... ,would we be able to modify that tech to do what the Rogue Asurans did in "This Mortal Coil"? Have nanite constructed organic bodies (or at least Mandy.2 in stasis and make Ginn.2 on Destiny) to transfer the consciousness into.
Now, I think that covers all the "details" of my ideas.. I've had to stop periodically while typing to contend with one of my dogs who was trying to add her own two cents into the mix. But any way, thoughts/ideas of this? I mean, I don't know what the TPTB have..had.. in store for Ginn and Mandy and not sure if we'll find out before the finale, but these are just the random ramblings of a bored, geek and die hard Stargate fan! I look forward to hearing thoughts on this Have fun!
