That is unfortunate.

If you *own* the block, you can do anything you want with it.  I don't think
there is an issue with with routing, you just have to do it.  Then again, I
may be wrong.

Sure, a host modify (http://rs.internic.net/cgi-bin/itts/host) will set you
up.  If you can, I'd try to overlap service so when things fubar, you can
always fallback to pieces-parts 'till you can figure things out :)
