The fact that the most famous
Cassandra was a prophet no one believed doesn't change the meaning of the name. A name's meaning isn't chosen based off of events related to a very famous bearer; it is derived from the root words that make up the name. So no,
Cassandra could not mean "Phophet [sic] of Doom."
