Well, exact same character is impossible because the repeat item is
direct postscript and hence not a character at all.
I copied the settings from scm/grob-description.scm but found the
resulting half and wholenotes too thick. So I ended up with quarter
notes like the slash-repeats and the half and whole notes with 2/3
line-width of quarter notes.
I commented it, so it is very easy to change if you want to change
something.

An example of how to use it follows.
The limitations are that improOn and improOff only allows for one
impro-thread pr. staff, but I guess that's all right. :)

improOn = \notes {\translator Voice = impro }
improOff = \notes {\translator SquashVoice = melo }

global = \notes { s1*3 \bar "|."; }

\score {
  <
    \context ChordNames \chords {e8:m7*7 a2.:m7 bes4:m7 b1:m7 e8:m }
    \context Staff \notes <
      \context SquashVoice = impro { \global }
      \context Voice = melo \transpose c'' {
        e8 e g a a16()bes()a8 g \improOn e8
        ~e2~e8 f4 fis8
        ~fis2 \improOff a16()bes a8 g e
      }

    linewidth = -1;
