I will test it, of course, and thank you very much for the offer.
The one thing that bugs me about this mod is the number of characters available -- 5. But, oh well, you can't have everything.
That's the thing: IWD is not geared towards replayability as much as BG2, and so is IWD NPC.
Besides, you see people arriving to IWD2 NPC forum and stating from the start: okay, I read your character outlines, and I didn't like them; will there be more characters? I want a different char! Nooo, I say, it won't do. Try these five first.
I could easily add a few more outlines, the obligatory dwarf, another female, etc, but it'll turn to obligatory "and now I must fill these gaps, and now I must complete his/her banters; gods, I am tired of this" soon enough.
Which is why I didn't go forward with "BG1 NPC in IWD" idea. Overall, I've done about 10% of writing for BG1 NPC, and with the exception of Xan stuff, it was a job to finish; an enjoyable one, but not pure, unadulterated fun, the way it is/was with Xan, Dungeon Crawl, or IWD NPC. Same with RE: at the end of July, I felt my energy was running out, so it was time to stop and release/code and test something others made, and release, not to push for quantity(though, yes, just like with BG1 NPC, RE materials are very diverse).
I believe in the rule "when the modder/writer is having fun, it shows". Let's hope you'll believe me when you see the end result.
