I don't agree that Alexandra would ever have become like Queen Victoria, as they were quite different personalities. For one thing, QV had far more common sense than Alexandra. They may have been similarly pig-headed, but QV was essentially pragmatic, and could listen to reason, where Alexandra was idealistic and believed what she wanted to believe, despite arguments (and evidence) to the contrary.
Queen Victoria never liked the idea of Alexandra marrying Nicholas and she feared that their marriage would be a disaster, and was she ever proved right!
