Ah… Then I would suggest the following thought experiment, however ungainly it 
may seem at first.

If someone with real Scheme-fu could build a function that took a series of 
moments and tweaks, you might be able to do something like

ms = \relative e'' {
   e4 e c d   |
   e e e2   |
}

correctionsEditionA = {
  \coolSchemeFunction #'(ly:make-moment 0 1) #'pitch #-2
  …
}
\markup { EDITION A: }
\score { \new Voice << \ms \correctionsEditionA >> }

correctionsEditionB = {
  \coolSchemeFunction #'(ly:make-moment 0 1) #'script #'staccato
  …
}
\markup { EDITION B: }
\score { \new Voice << \ms \correctionsEditionB >> }

...

Now any editor simply needs to build a series of tweaks which are "overlaid" on 
the original — like a transparency of bowings might be overlaid on [and easily 
removed from] a violin part — without affecting the original in any way.

This is WAY beyond my ken, so there might be [probably are] many tweaks that 
would not be possible.

Hope this helps!
Kieren.
