One of the wholesaler's we use in particular will probably make this next
to impossible.  I feel no need to mention names here, but they have been
very uncooperative in the past and I don't expect them to act any
differently in this situation.

That's an interesting idea, and perhaps I'm missing something, but the
only way I can think of that this could be done would be for the provider
who has assigned this space to put a static route in every single one of
their border routers.  That is assuming that they assign me a block out
of a larger announcement which would almost certainly be the case (unless 
they happened to have some swamp space they could give me). I doubt they'd
be willing to do that since it's certainly not very scalable.
