Would you cycle the gear?

I was with a student in one of our club Arrows. We put the gear down
and got green lights for the 2 mains, but not for the nose.

Would activating the emergency gear extension system have been an option to
extend the nose gear in case it were down but not fully locked?

Indeed it would have been. In fact, we did that, it being one of the
items on the checklist in the POH.

In that case, then I agree with what you did. The only likely situation
where the emergency gear extension would have left you without 3 wheels down
and locked would have been if there were a mechanical obstruction, and as
you pointed out it is possible that cycling the gear could have made the
situation worse in this case.

"Sort of..." Since the two mains were down and locked there was no
pressure left in the system. Pressing the emergency gear extension knob
does nothing but release pressure, and so nothing new would have happened.

The procedure would have been to RETRACT the gear (if possible), slow down,
pull the CB, and THEN push the emergency gear extension knob. If the pump
were failing, then this faster release of pressure might do the trick.
OTOH, if there were a mechanical problem, then there are any number of
hypothetical situations where it might not even come down as well as
before.
