It depends a great deal on the volume you're playing at. I can easily understand a 1x12 combo not sounding ideal, so the 4x12 option seems to be better suited to that spectrum. If you're playing so loud as to risk damaging either of the cabs you've listed, you're in a stadium with FOH support, so tone it down some. In any 'normal' clubs, bars or theatres, that amp with a 4x12 will easily fill the venue, even in those frequency ranges. I would, however, un-hook the combo speaker when playing with the 4x12; you will definetly not want it active at the same time as the 4x12. If the amp needs 4 Ohms, get an extension cab at 4 Ohms and switch out the combo speaker. I won't say much about the choice between the two listed, but the Mesa would be one heck of a step up, even second-hand, if you can get one from somewhere in Europe. Good luck with the project (but I suspect you'll be far too loud for my old cloth ears...). Edit: Our Eldest recommends the Harley Benson as better value for money, and well up to the task, and a bargain at its present price, compared to the 1960A.
