Dear Michael,
Have you looked at the work on acyclic models for crossed complexes in Section 10.4 of the joint book on Nonabelian Algebraic Topology, available from my web page?
www.groupoids.or.uk/nonab-a-t.html
Crossed complexes do not form an additive category.
I do not know a double complex analogue, as in your book, for these ideas.
Best
Ronnie

Is anyone aware of a non-abelian version of acyclic models that compares
simplicial objects (or functors) in a non-additive category?
