It would be nice to add an updated version with western style avionics, like an ILS localizer/VOR Receiver and newer radio and night vision goggles.
If it were possible, maybe even a new version all together like the L-159 Honey Badger which is used by Iraq/Czech and a few civilian operators as well. It would be a nice addition and jet alternative to the "Light Attack" theme coming with the A-29 and PC-9 coming this way. But nonetheless, bringing those listed above would be a good improvement.
