Yep, that's exactly the right thing to do.  Here's actual real live source
code from HyperCardIIGS, where we needed to do exactly what you describe:

  hyperCardResFile := startStopInfo.resFileID;
  {$IFC Internal }	{ convert the read-only resource fork to read/write }
    CloseResourceFile(hyperCardResFile);
    hyperCardResFile := OpenResourceFile(read+write, NIL, hyperCardAppName);
    IF _toolErr <> 0 THEN hyperCardResFile := 0;
    startStopInfo.resFileID := hyperCardResFile;
  {$ENDC }

This code worked just fine!
