Want to Keep G2 theme but link users with Drupal

I am overhauling a site of mine- I had an outdated handcoded gallery soooo I have been working on G2- love it. I had it looking awesome- then I got the bright idea to embedd it into Drupal - well I HATE it ....well hate is a strong word- but I intensley dislike it- I want to keep my Gallery2 theme but just integrate users between G2 and Drupal- can this be done? It looks revolting embedded... hey did I mention how much I DISLIKE the way it looks? Come on someone out there knows something..help a sista out!
