I'm confused as to whether this is a top view or side view.

You're right, 3 high is the correct height to make them. That, or a multiple
thereof, is the step height on most (all?) of the raised baseplates.
Interlocking will still be easy to do. I envision the interlocking being
between the 2x2 columns.

Well, this style is used in the US also. My description above is based on what
I remember of the Songo Lock in Naples Maine. The following web site has a
good description of how a lock is operated:
http://www.pigpen.demon.co.uk/locks.htm
I was not quite correct in what the windlass operates. It is used to open
holes in the gates or chanels in the walls to allow water to move into or out
of the lock.

You could use the 1x4 rack pieces with a worm gear. The hard part with
existing parts might be to hide all the machinery, at least if you want the
lower level of the lock to be as low as possible.
