Mazzy,
Failed ailerons wouldn't be a huge problem, assuming you keep the speed up to use the rudder. Even failed elevator controls could be survivable, if the trim system is intact, and even if it isn't there's a speed at which you'll be flying in trim anyway. If you want to simulate jammed controls, just hold them neutral in the axis you're failing (easier said then done) and use the others in place, whether it's trim or primary controls.
Very surprising that there's people out there who think that non-working (jammed) ailerons would nessecarily kill you. Best person to ask about this would be an aerobatic pilot or a test pilot - I've only done the control failure stuff in sims.
