I'm afraid I haven't played IWD2 (or IWD1) in a long time. I made all the code available if anyone wants to play around with it. I was running into difficult issues with some of the non-generic NPC's (the generic ones were manageable). The mod needs a lot of work to be enjoyable. For example, some of the IWD1 tactics don't work as well in the IWD2 engine.
I think the beta testers had the same experience I did. The mod works up to some point in the first act, and then it's unplayable (the opponents become impossibly difficult).
