Based on your list, I'm not sure you left much out. Perhaps the Washington National Cathedral? I've never heard that instrument, but have heard it is supposed to be nice.
Keep in mind, though, that the 32' Reeds you refer to can sound rather nice without a subwoofer because most of the tone of a Low-C 32' Pedal Reed is not at the fundamental, rather in the overtone series. Therefore, if the fundamental isn't reproduced, it's not hard to "trick" the ear into hearing the missing fundamental--much like Resultants do in Flue pipes.
That said, however, the 32' Contre Bourdon, 32' Untersatz, etc. will require a subwoofer to reproduce the sound accurately because the fundamental is much more essential to the tone than the overtone series. Of course, there are always exceptions to the statements I've made (and I'm sure plenty of people will take exception), but the generalities are true, while specific examples might not be true.
Have you considered visiting sites outside the US? I know I was VERY impressed with the 32' Flue at Ste. Anne de Beaupre in Quebec. It was not particularly impressive in a loud, powerful sense, but it had such a nice, filling tone that I've heard so infrequently, it deserved a stop-and-listen. I believe that is a Casavant & Frères of Saint-Hyacinthe, Quebec.
Again, thanks for your input on the OrganForum.
