Mike,

I do not like answering a question with a question, but have you tried to compensate for the yellow-orange light by adjusting your white balance? This just might solve the majority of your problem.

I do not remember the exact filter number to compensate for sodium vapor lighting and I am not where I can look this up, but you might look up Lee Filters or contact any good stage lighting organization and they will most probably be able to tell you the best filter from their published chartd. just a thought.
