He suggested that a string of 2 with a cheap charge-controller to make 48vdc, could be wired to the battery-bank. As a separate input.

Now, I am thinking, wouldn't that need to be ganged with the primary charge-controller, so the primary charge-controller could 'control' what is happening?

They will work quite well without any communication. Make sure the cheap controller has adjustable settings so that you can set absorb voltage to the same on both controllers.

While talking to one of them, I asked, so okay if I am going to have 2 extra panels, is there any aux thing I can do with them? He suggested that a string of 2 with a cheap charge-controller to make 48vdc, could be wired to the battery-bank. As a separate input.

You should be okay, charge controllers tend to work independent of each other pretty well, even in the past charge controllers with the same setting, will see slight differences and change settings at different times. I have argued that one of the advantages of the 'Whiz Bang Jr.' is that it will allow the Classic to see the extra input from your extra charge controller and help it adjust to properly charge your battery bank.
