The two measures was just an arbitrary choice.  You don't need to it to 
be precisely that; but for whatever amount you do decide on, all staves 
will need to agree with one another so things line up.

As for moving the engravers from \Score to \Staff, it would require that 
any specified bar lines be duplicated across the staves manually.  
Normally, it is sufficient for one staff to say something like \bar "||" 
and that will automatically propagate to the other staves.

It seems to be a recommended practice to prefer specifying elements like 
bar lines in a common, shared "\global" variable.  If you do this and 
reference the variable for each staff, then technically you are already 
specifying the bar lines on each staff.  The redundancy means that the 
score should work just fine with the engravers moved.

If it turns out to be unacceptable to move the engravers for the 
majority of your project, you could consider engraving this cadenza 
section as its own score which allows it to have an independent layout 
block.  This alternate strategy means subdividing your one score into 
multiple scores, so you would need to adjust things like measure 
numbering, indentation, and other spacing variables to get the final 
output to appear seamless.
