Ok, that's a lower bound. But is the force at any given distance
provided by the combination of 2 disc magnets on some object = twice
the force of one disc magnet at the same distance on the same object?
Or is it greater/less than twice the force of one disc magnet? My
quick and dirty model says "=", but "slightly greater" wouldn't
surprise me.
KC suspects that the JC's answer wasn't actually what the questioner
was asking.

If you put together 2 disc magnets, the resulting magnet is stronger
than either individually. This is easy to test if they have a hole in
the middle and you put a magnet opposing them on the top.

If you break a simple dipole bar magnet in two unequal pieces, how
does the strength of the pieces relate to the strength of the
original?
