What if we would have the background of a regular 2D / 3D instrument transparent or translucent, and arrange the layout like HUD, and laid over on the screen ?
I bet we can make the attitude / airspeed / alt / vsi gauges to only display the numbers without the ticks and the needles, and layout them like HUD with thier transparent background.
I thought it'd be a quick and straight-forward approach, but am I far off ?
Hope not.

The HUD is one of the very original pieces of code in the FlightGear
project. We had the hud implimented even before we were able to put
textures on terrain, before there was any notion of land use/land cover,
even before we had any 2d instrument panels, before there was a property
system, before xml.

The original hud code has served us pretty well, but we have learned and
grown so much as a project in the mean time. It would be a large effort
for someone, but I agree with Andy that it is probably getting close to
time for a complete rewrite.
