You can only load one mod at a time, so you would have to combine all of these into a single mod, which is not a small task as it would require compiling a custom .dll file.
Although I am not sure what next war contains, and if it has a custom .dll or not...
it could be that you start with BAT and then add in the xml and python content from next war. Though like I said I don't know what it has, so not sure how much work this would be. It might be fairly simple, or not..
