Here's the deal, as far as I was still interested, the game can stack mods onto itself, meaning that it is indeed possible to activate all your mods in an additive manner but the Command & Conquer 3 Tiberium Wars Control Center (1.07) probably still doesn't provide the capability. It is possible to do this manually but it is quite "dirty".
#1: It can be done by simply moving all the mods' .big files into one folder and creating just one .skudef file which would define all those .big files for usage.
#2: There is a logical problem with this. Two mods which modify same part of the game follow the "top most one wins" logic which means that all the mods defined in the .skudef file have to be extremely carefully sorted. Why? Because some mods may not work properly if another mods already modified data they use. Even if there would be a proper tool which could resolve dependencies of the mods there still could be mods which couldn't be stacked onto each other. The ZoomMapMod is mostly neutral and could be placed at the bottom of the list but that's all I can help with.
