I just found something while poking around in the Campaign's.

There are MANY files that are identical duplicates (Common) in each Campaign like Harbors.mis for example.
I used WinMerge to verify that all these files were identical. (A lot of dead weight and not to mention keeping them in sync)

I edited my data\Campaigns\CampaignProjects\Total_Germany.pj file and made the following changes.

[Layer21]
LayerType=0
MissionName=..\Common\Harbors

[Layer22]
LayerType=0
MissionName=..\Common\ScriptedPortPlanes

Mission Editor 2 was able to successfully load those files for the total Total_Germany Campaign from the Common Campaign without any errors.

Using TDW_GenericPatcher_v_1_0_168_0 I have the option enbled to show all game messages and there were no error's while starting the game.

I started a new Career and the Buoy's and Scripted Planes were working in Total_Germany Campaign.

Removing all those Duplicated files would greatly reduce TWOS MOD size (disk space footprint) making it a faster download etc.

This is a easy change to all Campaign Project (.pj) files that can be tested/verified quickly.

-=[EDIT]=-
Here is some more info on a test I am running now.

 

I made a test MOD that installs/removes campaign files.
Alls the files REMOVED_ are changed in the Total_Germany.pj to be read from the Common Campaign folder and game is running fine.
TDW Validator reports 2 Campaign errors, One for Monsun_Gruppe and one for Turning_Point. These 2 empty Campaign folders were added by EMCCD Mod and not related to this test.
Test performed on Stock Campaign other then my changes for test and NewUIs_0_7_4_2
