I imagine that such complex pieces rely on rehearsal marks of some form 
rather than bar numbers.

Your DSL might not need to be complicated by such matters, as it seems 
like one could use your system multiple times explicitly:

(I'm typing quickly, so my apologies if I have mangled your proposed 
function.)

%%%%
<<
  \repeat layout "..." << \new Staff {...} \new PianoStaff {...} >>
  \repeat layout "..." << \new TabStaff {...} >>
  \repeat layout "..." << \new RhythmicStaff {...} >>
> >
%%%%

This would let the first two instruments share the same layout while the 
other two can be unique.

I especially like this approach as it improves the locality of 
reference.  The layout DSL is most closely associated with what it 
affects.  Also, should one decide to rearrange the order of staves, you 
do not have to rearrange the order within the layout.
