The standards-based way of doing this would be to add

  @page {
      size: 6in 9in;
  }

to the brand's CSS stylesheet.  That's supported by at least
WeasyPrint and Morp.

If wkhtmltopdf doesn't yet support that, then a hacky approach
would be to have Builder.pm do an imperfect parse of the brand
stylesheet(s) before running wkhtmltopdf, perhaps as simple as:

   $_ = slurp($stylesheet_filename);
   s{/\*.*?\*/}{}g;   # Remove comments first.
   if (/\@page \s* \{ \s*
           size \s* \: ([0-9.]+[a-z]+) \s+
	               ([0-9.]+[a-z]+) \s* (?: \; \s* )?
	\}/xi) {
      push @wkhtmltopdf_args, ('--page-width', $1, '--page-height', $2);
   }

pjrm.
