For IR one would prefer a more stable platform.
Instead of glass I would simply replace the panel with a new, possibly metal, panel. Many new LSAs don't have glass, but their panels look so much better than the 50-60 year old plastics... Replacing only the panel will be much cheaper. Throw in some nice leather seats and decent digital avionics and you have a nice aircraft.
@slam: Havig many steam gauges looks way more impressive than 1 digital screen to non-aviators
The same holds for all the switches and CBs: more is better!
