IMHO it doesn't really matter which version of the ogre I do first. There's month, maybe years of time left until release of the mod and before that the ogre isn't needed anyways, right?!
Another thing is that I personally can be more productive, if I can switch between the single models I'm working on and choose myself what to work on at which time. There are days, where I want to work on this and days, where I prefer working on that. This kinda personal freedom is what keeps me going and prevents me from getting tired or bored. IIRC creatures are no priority at the moment, so it should be fine, if I finish the undead version first!!!
Also, as I create all my textures in Photoshop with all features on different layers, it does cost me only some seconds to turn an undead ogre into a normal one, or even make it a squirrel if necessary!!!
