Modding a Combo 2X12 Cab for Stereo/Mono (Speaker Rewiring)?
I think you should save up and buy yourself a cab and not mess with the wiring. I don't doubt you are good at soldering and a good tinkerer but with limited understanding of circuits, speaker load, and impedance, how will you know you connected it right before you fire it up? Remember if something is incorrectly hooked up it could blow the 2/90/2 output transformer(s) or the speakers in the combo. And then you'd be in worse shape than if you waited for a cab.
If this is simply not an option, I suggest a semi-permanent modification to the combo amp. I would recommend removing the wires to the speakers in the combo, conecting the speakers in series, and drilling a new jack in the back of the combo to connect to the speakers. Doing so gives you 100W handling at 16ohms (these are 8 ohm speakers right?). You will not be able to run the combo amp as an amp without removing the modification however and putting it back to stock form. But if you have a 2/90/2 I can't think of a good reason why you would ever touch the behringer again.
This is about the simplest I could suggest without worrying you'll fry yourself or the amp.
Another idea just popped in my head which may not require as much work ... Get a male to double-female "Y" cable. The male side goes into the 2/90/2 the female sides are paralleled and you can simply unplug both speaker jacks from the combo and into the Y cable, set the amp for 4ohms (again these are 8 ohm speakers right?) and youre good. Problem is I do not know of a male to double female Y speaker cable. You may have to build one using wire and plugs from a cable store online. Maybe lavacable? This would probably be the least intrusive and safest method if you can acquire the necessary parts. BUT please use a continuity test on a multimeter to be SURE beyond a shadow of a double that your cable is wired properly. If it's not or it fails as an open circuit (something disconnects) say goodbye to your 2/90/2 output transformer and hello to a 300 dollar minimum cost to repair.
When you weigh the liabilites out I STILL think a cheaper cabinet or used cabinet is the way to go.
