I was thinking along those same lines: have everybody S/R and stop work, Admin receives everything, (maybe even have the Admin make a backup to .zip file, just in case all else fails), Admin makes the change to Standard Translation, I assume Paratext would then ask to create the registration (click link and fill out registration in the registry), Admin back in Paratext should see the new registration, Admin adds the other members of the project (I assume he would be the only user to start with) and does S/R. At this point, I assume the project users wouldn't be able to S/R (since it completely changed under them). I assume they would have to delete the old project and S/R to receive the new project. I'd appreciate it if anyone could further confirm this proposal.
