When an approach specifies ADF REQUIRED (as in Rochester, NY KROC ILS RWY 4
or VOR RWY 4) is there any legal way to fly the approach without an ADF?
It appears to me that the only reason for the ADF requirement is for the
missed approach. Can the approach be flown leagally by requesting alternate
missed approach instructions that don't require and ADF?

No reason you can't use a GPS for this approach.
