Hi HRH
GWX installs JSGME with its mods collection so you know that will work.
The problem you will have is if you start your game from STEAM it will update your game and cause problems so it is important to convert your game away from STEAM.

Adding a bunch of mods without knowing the outcome of such actions is always going to be a bit dodgy.
You are at best should only add one or two at a time and check that there are no problems and they are doing what they should be doing.
It may well be that adding mods to your game because you like the sound of what they can do may not be compatible with GWX.
