Dear Gary,

I am not sure why you should not be able to use Montax for this. It supports 1UP-imposition (most other impo programs do not!) and you can reprocess the Xara PDF with different margins for left and right. The result is a normal PDF (with normal pages, crop marks and other additions are not required). I suggest you try their demo.
