@ATC Watcher I agree unless the government makes changes and make sure they get implied and rules are not bypassed it wouldn't help at all. The only focus of the CAAN is on Kathmandu and the bigger airplanes that flies in and out of it.
WAAS works pretty well in that area actually. Used it on 430 for 4 year there. Its a good aid, but without the procedures in place it is ofcourse of no use.
One has to make they own flight plans and procedures based on experience.
