It may just be random memory, but back in the 70's when I first learned about Alembic, you regularly saw that long scale basses had the point body, medium scale basses had the omega body, and short scale basses had the symmetrical body that Stanley became associated with. These were all Series basses, but they didn't call them that yet, because they were the only instruments Alembic built (Distillate came next, but must have been at the end of the 70s).
Before Stanley Clarke started playing Alembic, he was playing a Gibson EB-3. So, if there was really any correlation of which body a particular scale bass would have in standard configuration, then he would have had that small body first. Today, Alembic is all about options and customization, and that's always been a part of their story, but there did seem to be a very strong correlation of shape and scale in the past (and plenty of other things to do variations on).
That might be at least partly functional - a long scale neck on the small symmetric body would have a very serious balance problem, although even short scale players complain about it even now. As today, I think Alembic is extremely open to trying different things that you think you'd like, but unlike some order takers out there, Susan and the Alembic folks don't have any problem telling you that you're asking for something that won't work.
My mind is boggled that Stanley would have played a Gibson EB. From a construction and playability standpoint, those old Gibsons are very nice, but tonally, it's hard to imagine what Lopsy Lu sounds like coming out of that big neck pickup! Stanley is a very tall, thin guy with huge hands which even dwarf an upright bass, so it's interesting to me that he chose the short-scale bass when he went electric.
