John,
I've been following this thread with some interest. I'd like to find
out how you would modify the 'showpage' to duplicate a page at another
location. Short of re-sending the page information, bracketed by
'translate', I couldn't think of a solution.
If you do re-send the page information via FilePrint ala 2×4, I think
you can achieve your goal with a combination of imbedded PostScript codes and
modifications to the existing 2×4 macro (to place the PS codes and to
generated the print sequence).
If you'd like, I can give you the PS codes for doing side-ways/2-up
printing.

PS This is the first time I heard of a desire for this type of printing.
