High Guard contains rules for designing small craft, of which a fighter would be one.
IMHO, after a certain point, all fighters will start to look alike or similar from the view point of the game based stats. Really, the variations of systems you can put together at 100 tons or less is a finite number. Within 3-4 years I suspect we'll have seen the stats for every variation the MgT rules can provide.
With that in mind, I decided not to contribute to the "glut", and just started drawing designs/layouts/configurations for different fighter types, but all using the base 10-ton fighter stats.
BTW, I'm not trying to stop you from designing your own, just showing you an alternate path.
