Show videos in lightbox?

Hi, I really like this plugin, especially the random widget. But I’d like to play the videos in a lightbox for consistency with the rest of the site. Is that possible?

Secondly, is there any way to adapt the random widget to pick random videos from a post category rather than off youtube? I know that’s probably a stupid question but i’ve been searching for a plugin like that and I can’t find one. Thanks.
