Not really. To do what you want for an appreciable length of time, you
want a "sun synchronous" orbit phased over the terminator. This is
actually pretty easy to do with the earth (almost every launch from
Vandenburg goes into sun-synchronous orbit, though usually not over the
terminator).  But a sun-synchronous lunar orbit is much more difficult
because of the moon's far more irregular gravity field, and because of the
earth's proportionately larger perturbations.

I was thinking of a lunar equatorial orbit mainly because it's much cheaper
to get there.
