I have considered simply altering the $emailcontents variable but not having a strong understanding of the multi-part/text email stuff, I decided to ask first. I've slightly adjusted the email before, simply adding a line/variable that the client wanted included.  We'd still want to use the variables in the email, just reformat their display.

We send out emails, in complete HTML format, to our mailing list regularly, so I understand the display of HTML emails, I'm just wondering how I would start to alter the existing code in CWFunOrderConfirmEmails.php to allow us to re-format the confirmation email.
