That's tough... Pretty small room for your speakers. However, I'd be tempted in trying to use the room with the freedom to do as you chose. Even if it means building a second system, or replacing your large speakers with a good full range monitor or good small 2 1/2 way type floor standing speaker, if a second system is not possible.
This will allow you to pull the speakers more into the room vs. being forced to keep them close to the front wall, as well as keeping your listening position away from the back wall. This allows you to set up a more near field type scenario, if you will.
When treating the room, take pointers from those that know. GIK Acoustics is really great at this. They have been given any scenario you can think of to get great results.
