To the extent that you're trying to provide operators that should be
indexable, that won't solve the problem.
I'm unconvinced that these casts should be implicit anyway, as the types
are really considerably different than, say, int2 and int4 --- there are
no operations on int4 that "don't make sense" for an int2, the way there
are for polygon vs. box.
