No, and I think it can't be made to work since it's quite un-LilyPond-y.

What about something like (just a shot in the dark)

\edMods test \with {
  a = \with {
    m = 1
    mods = {
      \eMod 1/4 Lyrics #(make-music 'ExtenderEvent)
      \eMod 0/4 Voice \(
    }
  }
  b = \with {
    m = 2
    mods = {
      \eMod Score \tempo "Allegro" 4=135
      
...

?

I think interface improvements to the edition-engraver can always we considered.
But we would have to have a thorough discussion in order to be sure they are 
really an improvement. I mean a construct as I wrote above can easily become 
unwieldy and confusing too. I think there's always a tradeoff between clarity 
of structure, number of keystrokes etc. Such a nested structure tends to be 
more prone to problems through nesting brackets ...

No idea about that, but I think it's quite a way to go until we can consider 
this.
