I'm no mathematician, but I don't see how either operation gives you
a random number. Both operations are commutative and hence must lose
at least one bit of entropy, and neither operation fully maps to the
range of numbers (the latter function mapping quite sparsely) in the
order of your 'random number'.
Just use each pile (or successive 'throws' of the same pile) as a
digits of increasing significance until you have a random number of
the desired order.
