Really nice.

1) You know that you can give dynamics their own directions? So you can simply 
write (in rightOne):

<bes bes'>4^\<(

instead of 

\dynamicUp
<bes bes'>4\<( ...
\dynamicNeutral


2) Resetting the tie direction to the default in rightOne is much simpler than 
you thought. In particular, \voiceOne simply sets (i.e. does the same as 
\override) the 'direction property of several grobs, including Tie.
So, to get the oneVoice-behaviour, all you have to do is to revert the Tie's 
'direction property to the default:

tweakSix = {
  % Simulate \oneVoice style ties
  \once \revert Tie #'direction
}

<a a'>4 <b b'> \tweakSix <cis cis'>~ q <d d'> 

Note that now the \tweakSix has to be placed right before the tie's start, 
which is what one would intuitively expect.


3) You manually use \oneVoice ... \voiceOne to get proper rest merging. 
LilyPond can do that automatically:

I thought that this function has been included into LilyPond, but I can't find 
it anywhere...
Ah, it's been started, but never finished:

4) Thanks for tellung us about the tupletSpannerDuration... I wasn't aware of 
that and always copied dozens of "} \times 2/3 {" strings when I wrote some 
string ensemble works... This makes life way easier! Amazing, even after years 
of using and developing LilyPond, you can learn something new any        day!

Cheers,
Reinhold
