Lightbox with Montage stack link?

I love the new link option in Montage 2, but am trying to have the linked item (a youtube video) open in a lightbox instead of opening the linked video on a new page. I can link to a youtube video from Montage 2’s link settings in the info pane and this works perfectly opening in a new window, but cannot get it to open a link in a lightbox using TopBox from Will Woodgate. Followed the info on Will’s page to trigger it in TopBox but it is not working. Any help is appreciated.
