Thanks Carl,

Exactly the kind of solution that fits for me. Even better than my examples as 
the unisono parts are not constantly using the double stems which for this 
piece makes the visual appearance a lot less crowded (out of the 71 measures 
only two 3-measure phrases are non-unison).

I always had gotten the impression that \partCombine would ruin all the rest of 
my templating, breaking the rehearsal midis, but your structure combines well 
with my templating habits. Just using \partCombine (with no additional meddling 
with the additional \partCombineXxx overrides) worked at least for this piece, 
and if not, I know how to apply them to get the desired output.
