That would require head tracking and probably a huge jump in system

Not a huge jump. PC gamers have a choice of several head tracking
systems which work with a player jumping about the living room.
Tracking a pilots head is less difficult since it need only track
pitch and yaw. Some IR LEDs on the glasses frame and a low-res video
camera would do it. It might even work with the "Track IR" system
supported by Condor Competition Soaring Simulator.

Head tracking would allow a very interesting 'augmented reality'
display of remote thermal detection data.

or you just buy one, second hand.......

You proposed system, if it works, can only track head position
relative to the glider. For a conformal display system the derived
head pointing angles need to be earth referenced and independent of
the glider attitude. Tell me a bit more about how you would plan to
implement that in a non complex system.

True. The easiest way would be a MEMS IMU integrated into the glasses
or helmet but it would need frequent updates - possibly from horizon
detection and a magnetometer.

For those interested in a sailplane HUD, I just ran across this:

I am not sure that I would want a HUD in a glider. It is distracting
enough trying to look out of the front window at the sky through the
various reflections on a glider canopy without having extraneous
instrument data out there too. The only gliding exception for me
would be an Artificial Horizon display - in that case the information
would be displayed in the same position as the natural horizon i.e.
the information displayed relates to what I am looking it (or would be
looking at if it weren't obscured) in the real world - similar to
military HUD display target data overlaying the real target.
