Nice to see there's still interest in finishing this mod. As far as I know (and recall), after Q and GM, the mod passed to @Stoney, who shared it with me. I did some work on it (in early 2011, according to my old DMs from LucasForums). So far as I remember (and the files say), I wrote some descriptions for the masks (and probably corrected typos etc in the rest), and Stoney and I set up the merchant to work. Stoney, I think, added SG to the Galaxy Map (I remember experimenting with this, too, and with adding an item to Goto's Yacht to allow access). I also worked on the Scrapyard Skirmish scripting, though I don't think we ever sorted it out. Eventually we passed the files on to @Fair Strides.
This is the archive I shared with FS in early 2012-ish, which, amazingly, is still there: https://www.box.com/s/c6mxh8h5epzp6jwaeh74
The model files are almost certainly out of date, and the scripts are likely a mess, but if they're of interest, they're here.
Stoney and I also talked about potentially adding some gameplay where you took control of a droid to fight, and gradually got access to upgrades and equipment to improve your droid as you went on, but we never got further than vaguely talking about it. Life got in the way, as it does.
