Not a scholar either, but a quick web search turned up this [1].

C2 seems to be "Lesser Mode Imperfect, with Imperfect Time".

I would suggest using "timesig.C44" as it stylistically matches the 
number two from Emmentaler.  Otherwise, use a two from some other font 
to match mensural C.

To match the alignment, you need to use \vcenter.  Consider:

%%%%
\override Score.TimeSignature.stencil =
#(lambda (grob)
  (grob-interpret-markup grob #{
    \markup {
      \musicglyph "timesig.C44"
      \vcenter \number 2
    } #}))
%%%%
