Sambhu prasad dhungel "Ashukavi" has written (translated) mahabharat in nepali. It is in chhanda ( lyrical poem), it is really wonderful and thick book.

if you are looking for ramayan not only bhanubhakta but  Ravilal has written ramayan in nepali too, which is not as famous as of  Bhanubhaktas Ramayan. It is written in folk tune and nice.

There is whole geeta written in Nepali called " Komal geeta" hope you got your answer.
