Yes, I did it once.
I had to use an override file in an override folder to make it work - there was a poster named stoffe-something that gave me the file when I asked about the same thing, here, many moons ago. That thread is lost to time, but....yeah. It was funny.
I still have the file, if you want it. I think all you had to do was put in the folder and the option would show up under the right circumstances - which I think was when you first originally get him/can do all those convos that give you influence - but I don't remember 100% for sure.
Edit: The file isn't a 'mod' in the sense of say, giving your chr. powers to choke anyone anytime. It's just a file that sorta restores the convo option (or part of it) that was taken out, or something.
LC, you kick ass.
