It's as CompleCCity noted, first there's license issue, but since both IWDW and BGW use CC-BY-SA, they compatible with each other; then the permission, while I can't speak for other contributors or admins, I'm fairly sure they don't mind, I myself welcome your uses :-); finally the attribution, well strictly speaking you should give appropriate credit, provide link to source, and indicate if any changes were made, but I'll just leave the choice to you, whether and how you give credit is totally up to you.

Sadly, I have little knowledge with IWD, played the game fewer times than BG, and as you can see I'm even not as active here as before due to some reasons, but I still check here from time to time, so feel free to ask and I'll do my best to help.

There're indeed some wikis separating game titles from the same series, but personally I dont't think a dedicated IWD2W is a good move. There was a BG2W before, but later merged into one with mutual agreements. Considering the similarity and consistency, I'm more for an integrity IWDW.
