I've an Proto ABBBBA set, which has a powered A, two powered B, two dummy B and a dummy A. The old NP set with a couple of units added. Can one use an ABA Proto2 upgrade kit for the powered A and B, then a regular Proto2 diesel upgrade kit in the second powered B, and run the string as a "lashup?" I've been told one cannot use two slave units off the master unit for the two powered B units ... how could the lighting in the trailing dummy A be handled with such a setup?

I can't see why you can't run them in a lashup, the trailing dummy A would be the handled just like it would in an A-A lashup, right?
Have you tried creating the lashup and see what happens?
I would think you could run a PS2 powered A and PS2 slave B tethered together and a PS2 powered B tethered with the A dummy. The PS2 powered B unit would control the lights and coupler in the dummy A unit. No tether would be needed between the other units.
That's a good approach Joe! Maybe the existing Proto tether would have enough wires for the Proto2 upgrade lights in the dummy A, markers, headlight, interior light and mars light.
