Can BLAT imbed a pdf in the body of an email?

I want to send a report with a column of dollars in the body of an email, not in an attachment.  To make sure the dollars line up in any mail viewer, I think it needs to be a pdf.  If the mail viewer uses variable width font, the column will not line up.  I don't want to use an attachment because the email will already have one attachment for each line in the report (list of invoices).  Any ideas?
