I dunno if anyone else has seen this but y'all may want to check out this;
RPG Gamer.org CEC Ship Designer
Its a Fun little tool to let you mix and match parts from various CEC YT-series (and some) to build a wacky YT-series of your own.
It can also spit out a set of stats for said ships, but its for D6, but at the very least it gives a spring-board for creating ships for FFG!
