For Fun Shaundi just make a clone of old Shaundi's body and input Fun Shaundi VR's conscience into it.
And do a Similar thing for CID, give him a clone body (let him have a run at Image as Designed to create his character).
And drop clone bodies in the old time line to replace people they want to stay alive (Lin, Carlos, etc).
This way the old stories stay the same (don't corrupt the time line).
Actually, with Zen Tech you could just pull the Mind from the bodies before they die and then place the mind into a clone body (Star Gate Asgard spoof).
Grab up Oleg before the planet goes pop, and Burk just so Matt doesn't go nuts (teleportation was in Zenyak's wrist unit - in mission 2).
What I don't get is with all of the Zen Tech, they don't list anything about Terra-forming.
Or Planet Reconstruction, a sustained black hole shot into the center of a debris field and you have a planet. Just remember to turn the black hole off before the planet/material is sucked into it. Use of the Shield tech could be used to push/pull material into the are you plan to make a planet... yada yada yada.
