I’ve updated the Bomer premade with a matching Coppermine theme. I tried to make it work before, but somehow, I couldn’t, so I released it as a stand-alone WordPress theme. But I finally had time to get back to it and try again, and I managed to do it this time. The stand-alone $7 WordPress is not available anymore, but you can get it as a WP/CPG package for $10.
You can buy it on Sellfy, or contact me. I’m still open for header and/or color scheme customization for an extra $3.00.
