I wouldn't worry about the door handles and key hole issues. I've never heard anyone failing safety inspections because of those. Air bags are not permitted, but I don't think most stations really get that in depth. There is a Reconstruction Permit process that can get detailed. Look that section up on line in Hawaii gov't pages web site. "Recon" is needed prior to a safety check tag, and it deals w/ dropped suspensions, larger than OEM wheels....good luck.
