Yes.. I have seen people done that.

Did yo just use your passport or you submitted english version of the birth-certificate from Nagarpalika? These days Nagarpalika of Kathamndu, Lalitpur issue english version of your birth-certificate based on your citizenship card. But they need to see the tax payment slip of your residential house. Overall it's not that hard to get it.

In my time, they never asked for birth certificate.. just passport photocopies did the job. Probably not now.
