Avery,
        I think the force of driving the pin would certainly seal the
end grain of the lumber and stablise it. How loose is loose? CA works
great on loose marginal! but if you are needing quite a bit of gap
filling I think the epoxy approach might be better, Since you mention
plate bushings, water will get past them very quickly, so don't fool
yourself that they will have protected the pin block. With this type of
problem I would be inclined to replace the bushing as well, A new one
will reduce the tendancy for the pin to flagpole and give the hole in
the block a bit more stability. If you find you are forced into over
size pinning I would hand ream the hole to get rid of rust and garbage
that may have washed into the hole.
Good luck Roger.
