As soon as she was a queen, she went around the country.
Can I change this sentence into ''no sooner----than''?
For example,
No sooner was she a queen than she went around the country.
I raise a doubt that the word ''was'' is a linking verb and we can use it for inversion as inversion can apply for ''auxiliary verb''.And the word ''she'' is a weaker proper noun for ''copula inversion''.
