Some of these can have their inserts rotated into as many as four
different orientations. Often noted by a W through Z. Presumably to let
you have several cables with the same number of pins that are not
interchangable.
Can these rotations be changed in the field, or is this a factory only mod?

It depends on the construction of the connector. The older ones from
WW-II to 1970's were often easily disassembled with a circlip holding
a 2-piece phenolic insulator in the metal housing. Some of these even
had notches molded into the phenolic so that a moment with a file could
open up a notch to allow repolarizing the connector in the field.
Waterproof connectors and some other styles have "rubber" insulators
either molded or crimped in, so they can't be altered.

There may be a series where the keying may be modified during the
end-user connector build (pinning, backshell, etc.) but I'm not aware of
any. Far less likely would be a connector that could be realigned post-
assembly. All of the ones we've used have the keys machined into the
housing, with a master key at 12 o'clock.

I'm assuming that you're talking about MIL-5015 style connectors.
Dunno about Cannon (note spelling). I've always used Amphenol.
Amphenol can, in most cases be configured, in fact you have to order
connectors by the part numbers of the individual components, which is an
obstacle course. BTDT.
I guess the Cannon product is similar, but the catalog requires Acrobat 8,
so I guess ITT-Cannon won't be getting my business anytime soon :-|
You *must* have the catalog, else you'll not get what you expected, BTDT,
too.

Factory only anymore, what with elastomeric inserts being glued into
their shells with indexing per customer request.
If you've happened onto a bunch of old Cannon plugs with rigid
inserts, then my experience is the same as Jon Elson's, and once you
remove the circlip securing the two-piece insert into the shell you
can easily file away the "cherry" blocking the indexing you want.
