That is the plan. I just took a look at the model and I think Im gonna make a little “video tutorial”, so you can watch me while I explain.
I already spotted some things that fall in the category “Ok to to if modeling for a still image, but not for gaming”.
While the model (seems) intact, I got some interesting errors when opening it initally 
(But that could be related to the way the FBX was exported)
and thisone made me really raise my eyebrow 
But I finally managed to import it “intact”, so tonight Ill have a go at it
