Mcintosh MC275 monoblock different version


Hello, i could not find a solution for my question. i have an original mc275 and a mc275 Commemorative edition. Ideally i would like to have identical amps to do monoblock. However, it is fairly hard to find either the original MC275 or CE edition...i could sell both and get either V or IV...but for the time being and budget issue, i may just stay put....so if i mix them together, will they sound OK? 

thank you all

@yogiboy: your suggestion will only work if the OP's speakers have a split crossover with separate + and - terminals for the bass and mid/highs. Good idea though!
