I'm not sure what you mean by "animation replacement". If you think I should try to import Bodhi's animation instead of using the sinuous girl, that's fine, and you're welcome to say so now. Ditto for the Githyanki. However, they're not there now because I can't get them to work, not because I'm being perverse. Animations are, in general, hard-coded.
I meant general things like that, yes, though not just for Irenicus and Bodhi.
If I understand correctly the problem is that IWD2 will not accept some of the extra animations from BG2? This may be a stupid question, but couldn't the animations from BG2 be extracted (aren't they stored in .BIFs? There are some .BIF extraction programs floating around) and renamed so they override some useless IWD2 animation?
E.g., Bodhi's current animation is a Yuan-ti sorceress. Could you extract her BG2 animation, call it whatever IWD2 calls the Yuan-ti sorceress, and put it in Override, as there are no Yuan-ti sorceresses in BG2 so Bodhi would still be unique?
Also, could the BG2 lich animation be used if possible, since I reckon it's much cooler than the IWD2 one.
If this is not possible, I have a few other suggestions. Gibberlings look like svirfneblin from (IWD1) at the moment, they only appear in a few places so why not replace them with goblins/kobolds?
Vampires look like Wights, could they be given human avatars (mage? mix of males and females) in black with pale skin and dark hair?
Also, there is a Ghoul animation but currently Ghasts look like Shadows. Could Ghasts be made to look like ghouls (or perhaps use the Wight animation instead)?
One other small point- the moose in Waukeen's Promenade looks like a cow.....
