I would use WinMerge on the two files in question. That way, say you have nix's file on the left, and Ralles on the right. Nix's file has the changes for the calls that add the "Hollywood" missions back in that are needed in Ralles, but there might be other differences as well, that need to be changed. You just use the Alt - Right Arrow key combination to make your changes, then Alt down arrow to go to the next difference. Skip the differences you don't need to do.
If I remember correctly, the actual mis and tsr files are their in their folders in the PatrolObjectives folder under the Campaign folder, and all you need to do is to enable that line in the PatrolObjectives.cfg file, but you might also have to alter their "AllMatch" lines to match the "ObjectiveCode" to actually have them assigned to be called by Flotillas.upc.
