The entire series was pretty well designed to prevent doing just exactly
what you are hoping to do

You've no idea why I'm asking, so please don't go assuming anything.

When dealing with docking and using shore power there are a number of
different combinations of adapters and splitters that might be necessary.
My question about the connectors was based on curiosity, not on
implementation. I'm certainly not interested in circumventing a properly
setup shore power connection. So I really don't need anything other than
what I asked.
