yes. all 30 purpose built -2s were just "birdcage" -1s modified with the radome, removal of the outboard right MG, radar instruments/equipment in the cockpit, and the small t-shaped radio altimeter antennas under the fuselage and the corresponding dial in the cockpit, as well as a small generator scoop on the right forward fuselage.. There were also 2 -1As modified in the field to -2 standard. However, simply adding the radome and maybe radio altimeter antennas should be enough for in-game.

*edit AND the -2s had extended exhaust pipes to reduce exhaust flame to help the pilot's night vision.
