Are 'Single 180 Turn From Downwind to Final' and 'Stall-spin on Turnfrom Base to Final' mutually exclusive?

To reply to the subject question in a word: NO.

You can stall and spin from any attitude or airspeed. All you have to
do is plan and execute it correctly or simply f*ck up the turn.

An AOPA article states that the AOPA Safety Institute and University of North Dakota are studying the "circular vs rectangular" pattern as a result of the NTSB "Most Wanted Safety Improvements. It'll be interesting to see what the study produces.

It's REALLY hard to spin while flying coordinated - if you know of a way I would truly like to know. It is also tough to stall while flying coordinated because it takes a very high angle of attack and you would really have to work it keeping the glider coordinated as you approach stall. The FAA is emphasizing an angle of attack indicator to prevent spins; I think what is needed is an audible flight coordination indicator. In our gliders we have a heads-up flight coordination indicator which is even better - it's called a yaw string (but you have to look at it and react to it).

Define "coordinated". No problem to spin with the string perfectly centered.

It's true in any glider with enough elevator, but the Blanik is excellent for demonstrating it. Shallow turn, very graaaadually slow it down, maintaining constant bank angle with aileron and keeping the string in the middle with the rudder. Pretty soon you've got a whole heap of out of turn aileron and into turn rudder. But the string is in the middle and the nose isn't even very high. And then BAM full-on incipient spin.

You just confirmed what I said: it is very HARD to spin flying coordinated (not that it can't be done). You also have to ignore your other instruments, particularly the ASI.
