It is possible, but not using the same address+port of course. One
solution is to have NSD only listen on localhost while unbound listens
on the external adress. You can then use stub-zone configuration in
unbound to make it use the localhost adress for lookups in any zone you
are serving from NSD.

This is what i do for my home network, for a production setup I would
rather keep authorative and caching DNS services fully separated.

No, NSD is an authorative only server by design.
