I'm poking with a stick in the dark :-) In this very case I'm playing
the advocatus diaboli.  I don't know enough details w.r.t. Gregorian
notation, so I simply comment on things that I find strange or hard to
grasp.

Sound sensible.

Yes.

Yes.

Yes.  This might not make sense at all, but it would fit into the
system.

Rather no.

BTW, my main reason for favouring `hollow' is that it is a visual
term.  I can imagine that a different, non-Gregorian notation could
also benefit from hollow notes.
