Lightbox Forms: Can we append custom HTML and why no prefill?

Wondering if anyone <cough>Sanford Whiteman​ </cough> has an example of appending custom HTML to a lightbox.  I'd like to put program-specific information on the top of the lightbox, such as "Fill out this form to learn more about ABC..."

Also, why no prefill on Lightbox forms embedded on a Marketo LP?

This is kind of a dealbreaker for using the Lightbox function.  It might be better to replicate with CSS.
