If that is the scenario it has caught more than one crew out before. The terrain out there is higher than the airport elevation by about 200'. If you leave the configuring until you are at 2000' altitude then you run the risk of the EGPWS going off. Joining at ROC you should be at 1700' and the ILS profile has you at 2000' at 5dme. If you are given track shortening from HORUS (often coupled with a high speed descent) then stick to the 3 degree profile. If you are cleared for a visual approach and you dive and drive to 2000' then expect the railway warning.
