Don't think so, at least not with this code - it's pretty much a
workaround. And the arpeggio-problem is still unsolved.
(Loud thinking:) Maybe NoteColumn could behave like rests, where we
have r1 and R1 already. Could be caused by setting a context-property
or the like.
This is beyond my depth , though.

You can try the combination
\newSpacingSection
\override Score.SpacingSpanner #'base-shortest-duration =
#(ly:make-moment 1 0)
Attached you'll find a little newer version of it.
Cheers,
Harm
