This, unfortunately, is unfixable. Other than modding the animation files, you really don't have a choice. You could play around more with the .efx files to turn the bullets and line them up, but I remember the emplaced gun being notoriously difficult to use. Not only does it have tons of damage, more than a deka would deal, but it doesn't draw properly. If you can find another gun, that would probably be best. Yeah. There is a certain point where you really can't do anymore with NPCs. Does it handle well at all in combat? Perhaps up the aggression and aim levels? Give it a rocket launcher? Just keep poking it. I think I knew this, but nice job! I don't use efxEd, the proper tool, so all I can really do is just blindly play with it.
