Power Brake as impedance "converter"?

OK - I've got an amp head with a 4-8 ohm max load (as labeled next to the output), and I've got a cab that's 16 ohms. I also have a Marshall "Power Brake" attenuator that has a switchable impedance setting - 8 or 16 ohms.

My question - if I set the Power Brake to 8 ohms (assume it's turned all the way up so that there's no attenuation), would it make it so that I could safely plug the 4-8 ohm head into the 16 ohm cab? (please don't say "try it and see" :D)
 
Why don't you just rewire the cab to the correct impedance?
 
It's my original 1986 1960A that goes with my original 1986 JCM 800 2204 head - I bussed a lot of tables to pay for those, and I assign a perhaps-unwarranted sacredness to them (although I did pull the "bright cap" in the head last year and I wish I would have done that in 1986) - anyway, don't want to mess with it. The head is a Yammy G-100 that I spent a total of $150 on, including tech work (not sure if I could sell it for even that, but who knows) - also, I want to keep the cab at 16, because the Marshall head is set to 16, and my son and his friends may or may not check those settings before they plug in :D I did pick up an 8 ohm 4x12, buy my son recently carted it off to his practice place, so once again I'm staring at the impedance mismatch issue.
