The note represented by the quilisma itself is of a normal duration.  Is there a way for the quilisma function to be modified to do this so that the midi comes out with the correct durations?

I'm unsure if this function behaves exactly as you would like, but it 
shouldn't be too much work to adjust to your preference. The 
make-relative macro ensures the returned pitches are correct if you 
enter your music in relative mode.

new_quilisma = #(define-music-function (notea noteb) (ly:music? ly:music?)

   (make-relative (notea noteb)
     #{ #notea #noteb #}
     #{
         \scaleDurations 3/2 $notea
         \scaleDurations 1/1
         \tweak NoteHead.stencil #ly:text-interface::print
         \tweak NoteHead.text \markup \musicglyph "scripts.prall"
         \tweak NoteHead.X-offset #0.8
         $noteb
     #}))

\score {
     {
         \new_quilisma e' f' g'
     }
     \layout {}
     \midi {}
}
