The bits of a (Boltzmann or not) brain’s beliefs is limited by the bits of the brain itself. So I don’t think this really works.
OTOH in my view it doesn’t make sense to have a policy to believe you are a Boltzmann brain, even if such brains are numerous enough to make ones with your particular beliefs outweigh non-Boltzmann brains with your beliefs, because:
such a policy will result in you incorrectly believing you are a Boltzmann brain if you aren’t a Boltzmann brain, but if you are a Boltzmann brain you either:
have such a policy by sheer coincidence, or
adopted such a policy based on meta-level reasons that you have no reason to believe are reliable since they came from randomness, and
even if a Boltzmann brain did obtain correct knowledge, this would not pay off in terms of practical benefits
