This is, you assume an input file like any of the *.brf files you've
mentioned, right?

It's still not clear to me what kind of formatting you need (except
modifying the number of characters per line). I can see the
following:
. Centering lines seems to be the standard markup for headers and
the like (in combination with the `.,,' marker)
. New pages start with `^L' (ctr-l) and have the page number flushed
right and moved into the margin by one character cell. This very
line is used as a normal text line but shortened in length by
three(?) characters.
. A new paragraph is indented by two spaces.
. The right margin is always ragged right.
Have I missed something? I think all those issues don't pose any
serious problems.
Formatting tables indeed will be an interesting issue, and I'm really
curious what kind of examples you'll show to us.

Yes. It should be straightforward to add two command-line parameters
(say, -rheight=... and -rlength=...) to the groff invokation. Is
there any other parameters which can be varied except height and
length of a page?
