That game was designed with an expansion in mind. The time setting just demands it. It's right between the two trilogies. Yet, no units from the later OT or PT. It would be extremely easy to add a "ESB/RotS" expansion, or even an Episode 3 expansion.
While an OT expansion is more likely, I can't believe LA would pass on RotS. SWGB had CC for AotC, and it would just make sense for LA to use RotS for an expansion.
