Mensural notation in a \markup command

[Dimitri Sykias]

I would like to insert the following mensural symbols using the \markup command 
in LilyPond.



In LaTeX, this can be done easily with a command like: \lilyGlyph[raise=0.6, 
scale=2]{timesig.mensural94} = \lilyTimeSignature{9}{2}.

How can I achieve this in LilyPond?

Thanks!
