You will save yourself much stress if you just have a U.S. Civil Surgeon from the USCIS list do a new exam for the I-693 as required. I'm sure that a greencard is worth another 150 dollars to you, spread over the decades you plan to live in the U.S. that price is nothing. Plus you've probably already found a gread doctor because in Seattle some doctors are charging almost $500!
USCIS does not want other medical reports they only want a fully complete I-693.
