Also providing a dampening effect on this transformation, are the weight of both oceans, which are now bearing down at both poles. Water is quite dense, being about 1/3 the density of the earth's top crust. Also, interestingly, it seems like the density and pressure of the atmosphere would be significantly greater at sealevel, especially at the southern hemisphere sealevel, though obviously not much of a factor in crustal transformation.
