This isn't quite as flexible, but I don't have strong feelings as
the number of colors is almost certain to be one of 2,4,16,256
(corresponding to 1,2,4,8 bits).

With Batik no all of the rendering is pretty hard coded to 8bits
per channel of RGB and Alpha. Even in general this would be extreamly
difficult as there are lots of places where blending takes place which
is just a bear to do in indexed color spaces (gradients, opacity,
filters, ...).
One suggestion I might make if you really want to keep the number
of colors down is to turn off anti-aliasing (see the section on
rendering hints in the SVG specification).
