Hi Pierre,

LilyPond puts in-chord Ties in a TieColumn and performs her own thingy
according to the procedure 'positioning-done is set to, probably
dropping a user input for \shape.
Imho, best you can do is: set positioning-done #t, meaning: "Dear
LilyPond, don't bother about positioning the Ties, _I_ will do it."
Ofcourse you _should_ do then. :)
I.e. the Ties needs a direction. In your example it's done by
\voiceOne, you could use direction-modifiers ^/_ as well.
Now apply \shape where you want.

Example with some crazy values:

music =
\fixed c' {
  \time 3/8
  <b -\shape #'((0 . 0) (0 . 0) (1 . 0) (-2 . -2)) _~
   g'-\shape #'((0 . 0) (0 . 0) (1 . 0) (-2 . 2)) ^~
  >4.
  \once \override TieColumn.positioning-done = ##t
  q
}
{ \music } { \music } { \music }

HTH,
  Harm
