Model help from the experts please.

I want to create a Dragon Statue from an existing Dragon model and replace the Naga on the Altar of Depths with it. I don't have access to 3D Studio. My tools are MDX Text Editor and War3FileConverter. I've used Rhino3D to edit the Beta Azure Dragon model to the position and shape I want it; now how do I go about adding it to the Altar? I probably need to strip it's animations..how do I do that? Do I add the model to the altar via attachments, or what? Please help.
