From my days as a Facilities Engineer (1970's), I recall that sodium vapor lights have a very limited spectrum. The low pressure ones especially so. There is just no blue end, so filtering out the red-yellow would leave practically nothing.
They're not like flourscent which has a discontinous spectrum but does have red and blue parts.

Indeed.

The "no blue" applies to the high pressure variant (though it should read "almost no").
The rest of the spectrum they produce is patchy, with gaps, but with some of all colours represented. Maybe (never tried it myself) a tungsten balanced film, without filter, will produce better results. A filter used on daylight balanced film would do not much good,

Low pressure sodium has just the double D line.
There's only one thing you could do using a filter, and that is remove the little there is and be left with nothing at all.

Both sodium and mercury vapor lamps have what is called a discontinuous spectrum. There are no filters which can produce satisfactory results. If you wish to get good images under such lighting conditions use B/W.
