I would go the other way with filters - avoid green but try yellow, orange and red - in an effort to reduce the contrast between the red hair and the pale face skin tones.
Red filters can be a bit extreme but often nude B&W photography is done with a yellow or pale orange filter - it gives the added benefit of reducing the appearance of freckles and spots. Lipstick and eye liner colour need to be considered as you can see some unusual and unwanted results
Green Filters accentuate skin imperfections - they can give men a rugged look but very few women appreciate such treatment.
Get your lighting as soft/diffused as possible - to minimise the lightingcontrast ratio in your shots
If its possible to do so, I have always found it useful to look through the camera viewfinder with the lens stopped right down - it accentuates the contrast to much more like the film sees - and with the filter in place you get some sort of idea of what the shot will look like.
Acros as a film is fine - but you might want to try over-exposing the film by a stop and shorten the development times accordingly (check the film & dev data sheet for details but it is likely to be around 15% less time)
Good luck and have fun
