Richard,

Well... That is, of course, a wonderfully articulated synopsis of all of
the problems one must consider when one is deciding weather or not the
"Classical Schmidt Camera" is the instrument one should use for
the research one is contemplating.

However, in this specific case, in order to meet all the critical points
enumerated above.... An F/2.8 Schmidt Cassegrain Anastigmatic Flat Field
Camera should do the trick.  and your Hasselblad back, should work quite
nicely... Now as to the date and time function...  Well... I defer that to
the computer wizards out there.
