Here is an example.  You were close, but needed to put the 
Pitch_squash_engraver 
in a Voice context, rather than a Staff context.

As you can see, in this example the pitch of the note has no effect on the 
height of the slash head, and transposition affects the chords, but not the 
note location.

Currently, there is not a good facility for using chord diagrams with 
transposition, but I hope to get one  implemented this summer, if I can get 
over the issues involved with changing computer systems.

I haven't tried any of the bowing indications.  However, staccato, ties, slurs, 
etc should all work in this notation.
