time-signature with notes like (3/"quarter symbol")

[padovani]

Hi, I'm trying to write time signatures with note symbols instead of 
"whole" fractions...
I'm trying to do that with markups but it doesn't like it...

that is the code I tried:

tsMarkup =\markup {\note #"4." #1.0}

{
 \override Staff.TimeSignature #'stencil = #ly:text-interface::print
 \override Staff.TimeSignature #'text = #tsMarkup
 \time 3/2
 c'2
}



any sugestion?
