This year I grew a lot of morning glories that grew over a system of
trellises I built early last Spring. I want to harvest the seed to plant
in other areas but many of the morning glories vines are still alive and
the seed pods, although closed, are still green and it appears the seeds
are still forming inside. Is it OK to just harvest these green pods and
place them in a coffee can and let them dry out?

The best time to harvest seeds is when they're fully mature and ready
to drop/fly away on their own. At that time, they've gathered all they
need from the plant (food, money, George Foreman grill) and are
prepared to set out on their own (except for phone calls for more
money).

Will the seeds form if
they get separated from the mother vine?

Some probably will.

The problem I see with waiting until the seeds
form in the pods is that there is a small window of opportunity to
harvest before the pods break open and the seeds blow away. It would be
very convenient if I could harvest all the seed pods all at once and be
done with it. Does anyone have insight on this?

Life would be much easier if everything happened at "convenient"
times. In my experience, this seldom occurs. It would be convenient if
daffodil foliage died back immediately after the blooms were done,
instead of becoming gradually rattier-looking for weeks. Assuming your
morning glories have been blooming all along, there should be plenty
of seed pods of sufficient maturity now. If you clean up the vines,
you'll probably find hundreds of seeds ready to disperse. Save those.
