Alternatively, if they were to get dense enough to even approach being solid, they’d collapse into one or more moons.

Isn't that a function of distance from the planet (the Roche limit) rather than the total mass of the rings?

The ring will have its own urge to turn into moons, and if has lots of mass, that moony limit will apply.
