As far as I know the only way to have them work together is to go in and edit them yourself. There are a few compilations up that some people have patched together already. It's been a little while since I've done it but I believe you have to extract the base_scripts with the gibbed red tools and then you can go in and edit the contents with notepad ++ or something. Like if you want to have mutiple talents per level and the no cooldown for the medallion work together you'd have to find out what lines those mods changed and go in and edit them yourself and then pack them back up and then they'd work together. What edits we're you wanting to combine? For my personal play through I have FCR2 no dark weapon effects, dark mode gear at any difficulty, and I edited the starting gear that I you get.(FCR2 has no CD medallion and all training skills learned included in case you didn't know).
