Something like second layout of this extension: joomru.com/plg/mv-gallery-for-k2.html
I have installed this extension but it has a problem that already described but not was solved: www.joomlaworks.net/forum/k2-en/41525-class-mvapp-not-found

You can create a custom override for the K2 Content module.
Apart from this you can look for an extension here: getk2.org/extend/extensions
