I think that is not correct. For unreal conditions the form is like this:
If + were + would + base verb
Eg. I were you I would buy a new car. If I were king I would raise the taxes.
Notice the verb phrase in the would clause is would + base verb not past simple.
The phrase "if I were" is used in unreal conditionals to express hypothetical or unlikely situations. The simple past tense is used in the main clause to show the consequence of the unreal condition. This structure allows speakers to talk about situations that are contrary to reality.
The tense used after "wish" depends on the context and the desired meaning. When expressing a present or future unreal situation, "wish" is followed by a past simple tense. For example: "I wish I had studied more." However, when expressing a past unreal situation, "wish" is followed by a past perfect tense. For example: "I wish I had gone to the party last night."
The past simple of "use" is "used." For example: "She used her new laptop to complete her project."

This sentence is a conditional sentence, specifically a past unreal conditional. It expresses a situation that did not happen in the past, as indicated by the use of "would have to."
The simple past tense of "had been" is "was" or "were" depending on the subject of the sentence. For singular subjects, use "was" (e.g., I was, she was). For plural subjects, use "were" (e.g., they were, we were).
