If Monarchy has to come back then i am okay with Shruti's daughter. But the need of a king is still not there. She will just be the name of queen. The queen shall be constitutional and the state should take care of her welfare not the otherway around. I know this is just hypothetical. In reality parties who ask for Monarchy do not even get 1% of the total vote so i do not see any chances for Monarchy unless Prachande decides to revive it.
