What is the easiest (cheapest and quickest) way to stop
the coolant from going to the water heater and back?
For now, I just want to eliminate at least one possible
source for a coolant leak.
I intend to eventually remove the OE heater and install
one of the AQUAH 6L on-demand heaters and then remove
all traces (other than LP lines) from The Money Pit/Pig.

Mac,
Different folks have conflicting meanings for "cheap and quickest"
I would consider plumbling it like coaches that do not have the pre-heat option for the water heater. Eliminate the tee at the right rear of the intake manifold and run the 5/8 inch hose direct up to the heater (through your vacuum operated cut-off valve) and run the 3/4 inch return line from the heater direct to the engine water pump connection. You could then remove all the line and fittings going to the heater and seal the holes in the floor where the lines enter (usually under the refrigerator).
Real quick -- use a locking vise grip to pinch off the hose.
Or install valves in the lines going to the water heater. Of course I always think "more connections, more chances for leaks"
Does this help?

I would not recommend pinching off the hose or putting a shutoff valve on it.
You could eliminate the hoses to the back and put a short loop from the back of the passenger head to the front. You can just cut one line and use it for the loop.
This way you are still circulation coolant from the end of the head rather that just stopping it off.
