I could do that, but first I'd need some free time to do it. Currently, I have college so I can't really spend that much time doing that. So far FOOK NV doesn't really touch anything but the vendor leveled lists, as far as I've seen. The weapons and armors don't appear in the capital wasteland. If I convert FOOK2 to work with TTW, I imagine I would have to edit the large list of armors that it adds, same for weapons but I imagine those weapons do not even have iron sights since they're FO3 weapons. I have no idea how I'd go about changing the weapons.
One question though, what exactly would constitute as a FOSE script that would need to be fixed for NVSE? I know how to recompile the scripts but I haven't ever fixed a FOSE script. I do know how to make scripts though, that should be no issue.
