No, it won't, at least not under the Standard Model. First, you cannot 
dissociate quarks at all. Second, virtually all nuclear fission events 
>from about nickel on down to helium require energy input, often extremely 
substantial input; in a universe near thermal equilibrium, that energy is 
not available, so you're still going to have most iron nuclei hanging 
about. Third, un-ionized atoms are still going to be relatively common, in 
a ratio to free protons and electrons that depends on the temperature and 
particle density of the thermalized universe.

BSM theories that include proton decay can change that outlook, but given 
that the experimental lower limit on proton lifetime is 10^33 years, you're 
looking at a few umptyfantasticajillion years to reduce the universe to a 
uniform sea of low-energy photons and neutrinos.



Ouch, ouch, ouch, ouch!  Okay, I think my brain has officially exploded.

Peace,
