At my work I saw a Nepali surname and the first name was Hricha.
It was for ऋचा. it's my bad could not translate roman Nepali properly.

Hope you will find one which one is easy to pronounce as it full fills your criteria.

Asti bharkhar kattu bro ko Nepali naam ko bishayako thread nai delete bhayo..... Pheri bhand bhailo nahos
Anyways, how about Maya?........short, simple, sweet authentic Nepali name.

I assume you are dad.
To resemble your name, I would recommend - "Bastardicka". It is girlish and Americanized name.

Maili (as in Miley cyrus, but spelled like Nepali)
Sara (as in Sarah)
Keti (Katie, but this one is stretching it)

don't name your children that start with letter A. Instead of saying अ / आ they pronounce it as A like A-mit for अमित. nowadays every other Nepalese children's name start with A for girl or boy. like parents don't have time to search for names beyond letter a.
