Unfortunately the saga build doesn't have the hud controls, but the cockpit itself is ok. I.e. the gauges will appear like they do in freespace/saga not placed on actual controls.
As for the cockpit shapes, I'm sticking with the stereotypical cockpit tubs, like those of nearly every real-life fighter and quite a few of sci-fi fighters (most of wc, xwing, ywing, a-wing, b5 thunderbolts). The canopy bottom has to be somewhat flat so that a cockpit can easily be placed in it.
Right now I'm doing some work for Deathsnake and once that's done i'll get back to work on the cockpit and the Seagull corvette.
