It's theoretically possible. Just as possible as it is for all the matter making up Earth to spontaneously quantum tunnel away.

Though interestingly, the first Jaeger, Brawler Yukon, was deployed in 2015--one year after Godzilla and the M.U.T.O.s fought. So it would be possible to say that Godzilla was one of the kaiju that appeared during the 2013 invasion, though independent from the Rift and its aliens.
