Could another force appear in the future as the universe cools down?

If the forces supposedly started off as one great "super-force", but split apart early in the history of the universe as things cooled down, is there any thought that one might just split off again at some random point as the universe gets colder and colder, leaving us with 5 forces and a radically different world?

Probably not.  Things are already pretty cooled down, there isn't that much more cooling to do in the grand scheme of things.

We know that electromagnetism and the weak interaction become a single unified force at high enough temperatures, and the popular hypothesis is that this also happens for the strong interaction at even higher temperatures, and possibly even gravity at higher temperatures still.

The unification of forces is only apparent when there is enough energy to preserve a certain symmetry, and *anywhere* below that energy, the symmetry will be broken and the split forces will be obvious.

However, we can do experiments with all of these forces at ordinary temperatures all the way down to absolute zero, and there is no indication that any of these forces break down at these temperatures.

TL;DR:  Almost certainly not.
