Sorry - taking the boat to even-more-shamelessly anounce
extradict.extratuple.defaultnamedtuple - in the newly released

extradict v. 0.2.5

https://pypi.python.org/pypi/extradict/0.2.5

It allows one to build an default-paremetrized namedtuple by passing
a sequence of 2-tuples with key, values, or, on Python 3.6,
pass in the default values as keywords to the defaultnamedtuple factory.

(The  "extradict" package, with a faster reimplementation of
namedtuple already existed, of course - maybe someone can pick some other weird
idea I have into there to put it into more day-to-day use)
