Plan B: If Blender does not work for you or it adds too many polygons during the boolean union/CSG process, you can always export the DoGA model as a SUF file, read that into Metasequoia LE, clean up the geometry, and export that as an .X file.

That how I make a lot of my game models. I do the rough design in DOGA and the finish work in Meta.
