I would love to built an updated version.

This is really not out of the realm of a dedicated hobbyist.

The switches and keycaps can be ordered from quite a few vendors.

Also, custom circuitboards are no longer difficult to design or produce in small quantities (especially separate left/right boards).

Use a Teensy to wire it together as a USB HUD device.
