You can add a line

!gensky [genskyoptions] | xform [xformoption]

To your scene file.

xform will do the translations then. Check the manpage for it, it allows you to perform all necessary rotation, mirror and translation operations.

Just as Thomas, I still do not get want you really want to achieve and why not to use mirror modifiers and real geometry.

Cheers, Lars.
