Hello Damian,
Thanks for your effort. But look here:
\version "2.19.83"
{
\override Score.TupletBracket.bracket-visibility = ##t
<<
{
\time 1/8
% \once \omit TupletNumber
\tuplet 5/4 {
s32 s s
\tuplet 5/4
{
\stemDown
g'32[ 32 32 32 32]
}
s s s
}
}
\\
{
\tuplet 5/4 8 {
g'32[ 32 32 16]
d16\rest 16[ 32]
}
}
>>
}

The tuplet brackets are not all all what I need - refer to the image. Sure, I could mess with the bracket extensions and so on. But this solution, although clever, is tedious and fiddly (no disrespect intended) and I have dozens of these to engrave, so it's not very fluent.
At this stage I would be prepared to say this is not possible in lilypond (and I am more convinced it's far too idiosyncratic even as far as modernist music goes).
