I'd advise against spreading the cellos out too much, personally. It's not a good idea to have much bass too far outside the center. That tends to cause comb filtering when the listener is outside the listening position, and in a domestic setting that might also destructively interfere with upright bass and kick.

If you'd like to create some spread in the cellos as obelix suggests, a solution that would translate better would be to use a panned send to a Slap back delay. That would emulate localized early reflections and pull the cellos out a little further without risking translation/mono compatibility.
