Probably not in any reasonable time frame. Very roughly, rocks come in two broad types, they used to be called Sial and Sima. The Sial is a lighter weight rock high in silica. The Sima is a much heavier rock, richer in Iron and manganese.

The light weight rocks float as a skin on the molten more dense rocks.

Sedimentary rocks are an example of Sial, and Volcanic rocks of Sima.

This happy condition is likely to endure for a long time.
