Yeah, Eric---I've got an older Tone Works 2 x 10" cab (pre Genz Benz, I think---the Mosvalve people) that is wired stereo/mono depending on which jack you go into. I've actually never run it in stereo. If you need it, I may have a wiring schemo around for a switchable S/M rig like this. I think Genz Benz may still make something like this.
edit----you may be pushing it if you want the option of 8 ohm x 2 (stereo) or mono 4 ohm or mono 16 ohm. That one gives me a headache. But it's probably do-able.[This message was edited by Jon Light on 19 June 2006 at 04:23 PM.]
