Assuming "C 3" is intended to mean "4+3/4", then you can use 
\compoundMeter to set the time signature and then override its visual 
appearance.  Perhaps something like this:

%%%%
\version "2.19.82"
<< {
  \override Staff.TimeSignature.stencil = #ly:text-interface::print
  \override Staff.TimeSignature.text = \markup \concat {
    \musicglyph "timesig.C44" \hspace #1
    \lower #1 \musicglyph "three" }
  \compoundMeter #'(4 3 4)
  e'2 g'4 e' d' e'2
} >>
%%%%

Note that I used the "normal" time symbol "C" as opposed to the mensural 
version.  I think it looks better next to the numeric three, but you can 
use any of the glyphs in the font.  Or really whatever you want, since 
you have the full power of markup there.
