Well, the only speedbump would be the screenshots bit. I'm not sure if it would be smarter to make custom profiles and hop back into the 1.7 world, or to upgrade the current server and then do it.

custom profiles is faster and easier, that's how I access our server, another with a recent snapshot, civcraft (which is 1.7.4 because of 5 billion addons), and my singleplayer creative worlds in the pre-1.8 releases.
