I personally think that you should add two more legs to the monopod, rate the
film at 1/2 the ISO (or even 1/4 the ISO) to give the shadows some density,
then pull the development to tone down the glare of the lights. Or use a pyro
or catechol developer.
IMHO, pushing film (or even using its normal rating) in a high contrast
situation is just begging for trouble.
