First, modal auxiliaries like would are always followed by the base form of the verb, not by a past or past participle, so would had is never grammatical, (in any variety of English, as far as I know). You mean would have, as Kate Bunting said in a comment.
Second, using would in a condition (eg "If I would have") is grammatical in some varieties of English, but not as far as I know in any standard varieties: I would never say it, but many people do so nowadays.
Thirdly, would have is a sort of past modal, so If I would have been the president is a non-standard version of If I had been the president (past counterfactual). The present counterfactual equivalents are (standard) If I were the president, (non-standard) If I would be the president.
You first sentence is not a conditional, so its form would be grammatical if you change had to have; but there are other problems with it: completed is active, so it is not something that a wish can normally do; and in any case it is not the usual verb for what happens to wishes. I suspect you meant My wish would have been granted (or carried out).
