Could a black hole be held up from collapse to a singularity by the unified force?

As a black hole collapses, it becomes hotter and hotter. Wouldn't it eventually become so hot that the unification temperature for all four forces is reached and the gravity within the core of the black hole ceases to be gravity as we know it? The lack of gravity may cause the hole to stop collapsing and begin to expand. This expansion causes the hole to cool and gravity reenters the picture when it breaks off from the hyperweak force. This causes it to begin collapse again. This repeats until an equilibrium or quasi-equilibrium is reached and the core retains a fairly constant radius. A finite radius. Larger than zero. If the core is below the Schwarzchild radius (and I imagine it would be, given how much it would have to collapse to reach these amazingly high temperatures), then it would look like a classical "singularity model" black hole because it would still have an event horizon. The horizon would also keep heat from escaping the black hole to allow it to collapse all the way to a singularity.

This depends much on the behavior of the unified force, of course. Are there any predicted properties of the force? If it is a purely attractive force, then we can throw this idea out of the window. If it is repulsive, or simply a non-directional sort of thing (sort of like the weak nuclear force), then this scenario might play out.

Any thoughts? This is speculation, of course.
