Merge Level instead of Migrate?

I have a situation where I will have lighting saved in a level and will need 60 users merging that lighting into their project to use for baking. Creating a template will not work as the lighting will need to be updated as the project moves forward and it will need to be updated by 60 users again. Migrating will not work as those 60 will not be working on the same network, they will be working from local drives.

Is there any way to merge data from one project to another like you can in Max?
