Looking at the picture, it seems to me the only part which LilyPond
doesn't support is the special leger lines below the stave: though the
middle C superficially looks like a G, it's positioned as if it were
an E, but with the first leger missing (so the leger lines continue
the line-positioning pattern outside the stave).

The custom stave can be created by overriding StaffSymbol
#'line-positions, then it's just a matter of mapping the notes to the
correct positions with a custom layout function (via
staffLineLayoutFunction).
