Here’s one possibility:

%%%%
\version "2.20.0"

fixa = \tweak NoteColumn.X-offset #-3 \etc
fixb = \tweak NoteColumn.X-offset #-2 \etc
fixc = \tweak Accidental.X-extent #'(1 . -0.5) \tweak 
NoteHead.extra-spacing-width #'(-1 . -1) \etc
fixd = \tweak NoteColumn.X-offset #0.875 \etc

{
  <<
    \relative c''' { r4 \appoggiatura { \fixa cis32 \fixb b \fixc ais } b4 gis' 
e }
    \relative c'' { gis8 \fixd b gis b gis b gis b }
  >>
}
%%%%

Note that I had to unfold the \repeat in the lower staff, in order to easily 
apply the tweak to the correct moment. This is one of the [many!] reasons I use 
the edition-engraver: you can inject the tweak at an exact moment, regardless 
of how the musical elements in that moment were generated.

Hope this helps!
Kieren.
