I believe I have already switched batteries at least once with my other '69 Camaro, but I'll try it again to confirm. You mentioned a possible shorted cell -- is there a way to check this?
All the new regulators I have bought (and now failed) do not have a screw adjustment but I do follow what you said regarding how to adjust it. If it's of any interest all of my failed regulators check 64 ohms across terminals F&2 whereas the good one in my other car checks 45 ohms -- all other contacts have identical resistances for both the failed and good regulators. One thing I did not mention initially is that the regulator gets very warm along with the alternator -- this is not the case with my other car.
I assume that when you suggest raising the voltage setting the logic is to simply decrease current draw.
I'll give your advice a try.

I would change battery before doing anything else. May have a shorted cell causing overheat due to demanding high current for charging.
Check regulator cover to see if cover is screwed on or riveted on. Either way, the voltage is adjustable. Let reg come up to temperature, along with battery. Measure charging voltage, 13.7 is good, however, one can adjust the spring tension to increase the volts. If you find a screw, then turn CW to increase volts to 14.2 at battery. If no screw, turn off car, disconnect battery so as not to create sparks, use pliers to adjust the spring tension, adjust the base tab to increase volts(lengthen spring). Recover, reconnect battery, restart and measure volts.
Depending upon amount of charging, a screwdriver laid against the rear bearing of alternator, you will feel a magnetic field, stronger field = more current.
