Narrative:

During the ILS approach into mco; we encountered a sudden and violent 30-40 degree roll to the right at approximately 800 AGL. Although the precipitation was steady; until that point the ride was smooth. We did not receive any windshear alerts. It's possible that we encountered wake turbulence from the previous aircraft. We immediately executed a go-around and encountered moderate turbulence; frequent lightning flashes and heavy precipitation. During the climb; as we approached level off; the captain slowed the ascent but then continued above our target altitude most likely due to the turbulence. It was difficult to read the instruments and a fairly violent ride. We climbed approximately 280 ft above where we should have been. We corrected and resumed the map while ATC switched runways. We landed in heavy rain without further incident.it was the highest workload I've experience in my career. It was a little shocking to get rolled at such a low altitude but we handled the initial go-around fairly well. I think we were both distracted just trying to manage the aircraft once we encountered the turbulence on the go-around. As always; closer pilot communication and monitoring will help.

Title: B737 First Officer reported executing a go-around at MCO following a 'violent' 30-40 degree roll on short final. It was not clear if the roll was a result of weather or a wake vortex encounter.
