Hell you know, everything is possible, the real question is, is it worth the time and effort?
Apart from the disciplines files, dlg files, and py files, there would also be a lot of map changes to replace the new disciplines visual with the old ones. And of course, you would have to know the mod pretty well, gamewise, to make sure you don't forget anything.
Honestly, this might take less work to import and adapt the new events from antitribu to the UP or a other mod like CQM or CE, but it would still need a lot of work for something that you could never get to share, unless Lenuska agreed to it.
