right, margin dimensions only play a role in alignment and stacking margins

hm, is this a feature request? [should go into database then, even if i 
could implement it in 30 seconds; since you seem to like generating 
formats, i'll send you a new page-mar.tex -)]

This can be done already, but I was thinking of some slightly more

i have been playing with this some time ago, something \definedimension, 
but it's impossible to get thsi robust (esp in tex versus etex);

however, if you look into your beta cont-new.tex, you will see:

\beginETEX \dimexpr

\definepapersize
   [oversized]
   [\c!breedte=\dimexpr(\papierbreedte+1.5cm),
    \c!hoogte=\dimexpr(\papierhoogte+1.5cm)]

\definepapersize
   [doublesized]
   [\c!breedte=\dimexpr(\papierbreedte),
    \c!hoogte=\dimexpr(2\papierhoogte)]

\definepapersize
   [doubleoversized]
   [\c!breedte=\dimexpr(\papierhoogte+1.5cm),
    \c!hoogte=\dimexpr(2\papierbreedte+1.5cm)]

\endETEX

   texexec --pdfarr --paper=A4A3 --print=2SIDE yourfile.pdf

(prints ok from acrobat since it scales down to A4) or

   texexec --pdfcomb --comb=2*2 yourfile.pdf

is your friend.
