Richard.
I'd encourage you to look at the file "How to Create Accessible Adobe PDF
Files", available from the web site http://access.adobe.com/booklet.html
It discussed various paths and tools for creating accessible PDF or
transforming existing PDF files into TaggedPDF. We hope authors only need to
do the type of manual tagging that you describe the fix up minor problems in
the output of the MakeAccessible command.
The size increase in the TaggedPDF file will depend on the amount of
structure in the document. A single page containing only at table may see a
large relative growth; a multiple page document of text paragraphs may see
small relative growth.
