Well said, Frank, and the excess capacity of the radiator and fan system
has been proven many times by engine conversions, several in my
driveway. My I5 runs cooler under heavy load than the waterboxer under
normal load due to the more efficient water pump of the I5. The issue
comes down to how much the spare and cover will interfere and what the
result will be with a waterboxer and it's water pump.

Set a wheel on the front bumper of Vanagon and see how little of the
grill remains unblocked.
