If you’re interested, I’ve finished adding field group duplicators to my options page plugin. I would be interested in any feedback or bug reports before I merge it with the master repo. The duplicator basically does all the work of renaming all the fields and other necessary changes so that you can use the same field group multiple times and all of them will be automatically updated if there are changes in your master copy of the group.
