BUT the pump is offload when switched off. That may make all the difference.
Correct. Unless the cause of the original overheat problem has been removed (e.g. PTU selected off in post #5), then the system is likely to overheat again. See

In which case, simply turn the pump off again (to off load the system), and continue the approach (having made the appropriate landing distance correction beforehand.) You can't be any worse off.
Edit. See interesting fact sheet on Skydrol fire resistance.
