You'll like this one, it has all your favorite theories.
. Hugh Auchincloss Brown, who died in 1975, believed that the eccentric force of rotation of the growing south-pole ice cap would eventually become so strong that it would cause the earth to tip over 'like an overloaded canoe'. As it did so, the spin axis and equatorial bulge would rapidly migrate through the earth in the opposite direction, so that the inclination of the axis would remain the same. The cataclysm would take place in a single day, in which time the present poles would travel about 80° of latitude, or some 8800 km, so that the ice caps would end up near the equator.

Peter Warlow argued that a near-collision with large cosmic bodies (comets, asteroids, or stray planets), 1000 km or more in diameter, could cause the geographic north and south poles to exchange places on the spin axis, in as little as one day. He held that if the earth turned upside down within the magnetic field, this would explain apparent magnetic reversals.
