For the record, today yet another E39 owner has had problems getting the viscous fan clutch off ...

Here are some answers to leverage back to here so others benefit.

3. Use a screwdriver and wedge it into the clutch to hold it. (This is a cn90 trick)
I find the fan clutch tool works easiest with lowest risk of causing damage. Put a dab of anti-seize on the threads when you reassemble for easier future removal.
