Plus they would be spinning faster too, although I'm not sure how much that would assist in deforming the planets other than at the equator... and molten/liquid rock and such maybe have intra-adhesive properties such as the hydrogen boding of water. It would be interesting to see the full picture there. Also 20 million years would be from the star's perspective not the planet's, so the gas and dust wouldn't have even settled by then.
