Additional DCs includes a modified depthcharges.dat which has extra nodes added. Each of the extra node (as well as the original one) corresponds to a specific type of DC. The technical parameters of each DC can be found in the .sim and .zon files. So, basically, the mod adds new DCs to the game which will show up according to date and, of course, type of warship. Now
every DC has its own specific attributes (terminal velocity, hit points etc.). This is the main difference between Real_DC and this mod. Therefore, i don't see any reason why merge these two mods. Instead, you could modify any of the values according to your taste.
