Edit Woo order confirmation emails

My client sells custom embossed metal tags. The buyer inputs 5 lines of content which is to be stamped onto these metal pieces and they use the order confirmation emails to drive the manual entry process. The email itself shows the customer input like this for each of the 5 lines –

Line #: (line content)

The customer input is the parenthetical content shown above, while the “Line #” is part of the email boilerplate. The client has asked if that output can be edited as follows –

Line #: (line 1 content)

with the entire line in a larger size (perhaps 18 – 20px) and the custom input in bold, for convenience during manual entry. This would be a simple job for CSS, of course, but unfortunately there is nothing in the output which can be easily targeted with CSS! It’s just text lines separated by <br> tags. If only it would be simple to filter the output so that each line would be wrapped in a span tag! I would love any suggestions for how to deal with this – anyone?
