I asked Kiwibob to comment on the original question.  Here is his
response:
========================================
Yes it is possible, works very well, but may not be desirable!  I trust
that in Zone 5 the person is speaking of A. arguta.  If they graft, cut
scionwood in January & keep in a ziploc bag in the refrigerator until
the host female has leafed-out in Spring and all chance of frost is
past.  Graft high on the host to this year's growth (same age as the
scion) and train it to become a main cordon.

Downsides: It really complicates the pruning unless done as a main
cordon in the opposite direction of the female main cordon!  Grafts in
certain microclimates are susceptible to die-back in bad winters to the
graft union, then all effort is lost!  As a rule, I advise against
grafting any Actinidia except to introduce a new species until cuttings
can be rooted.

Happy Growing,   Kiwibob

Actinidia graft easily, so you should not have a problem adding a male
branch to the vine. The best time is late spring after the heavy sap
flow
has slowed. Since these are probably argutas?, if you graft high, the
graft
site could get lost in the vigorous growth, and you may have trouble
with
pruning. I would suggest cutting off the vine low, and letting two new
trunks grow back. One could be "green grafted" with the male cutting,
and
the other left as all female. That way they could be trained as opposite
cordons. If the root system is mature, they should grow back very
quickly,
and may flower the following year. Of course, by then, your lone male
may be
flowering well anyway.
