Answer:
It really depends on your perspective. This has to do with your own opinion. Do you think that having an official religion greatly affects the state of Nepal, or do you think that it does not? Do you think that, being religiously affiliated, that it will affect Nepal's foreign policy, national policy, etc?
The change of Nepal to being a secular state would not be a problem at all, considering that the state of Nepal is fairly balanced as of right now.
