Ugly, but if you install the Windows DWF printer, you could print the
PDF to DWF, then Xref that in.
It's not pretty, but it can be done. I used it this fall to approximate
a landscape architect's site plan. Get rid of the DWF as soon as you
can. The dwg was unstable as all get out while it was loaded up. Think
it has to do with the imagery etc.
