Is 6” too much for a spacer between these 30×12 cabinets.
My wife and I can’t decide.
We’re putting bookshelf on top.

That looks perfectly fine.
Two notes:
I would put a block on the back and the front. Since the cabinets are not screwed to each other you need to join them. This is as simple is a 6" inch piece screwed to wall then maybe one screw from each cabinet into it. On the front I would try to get two screws that are a few inches apart for each cabinet (would look for scrap 2x8).
I am assuming you will have a surface for your bookcase? The gap shouldn't really affect it either way as you should be getting some screws into those two walls (given your bookcase is in one piece, not two small bookcases).
Aesthetics-wise looks normal. Probably wouldn't even think about it if there were doors on it but unless you had these things custom made that look is about as good as it gets. I think you would be the only person that even realizes there is a gap (you can make this a functional hiding spot too).
Sorry I don't have enough points to comment yet so have to put this reply in the answer.
I had a vent coming out under the cabinets in the kitchen of my house for 20 years with NO PROBLEM (i.e. at the floor level where the kick-plate is). This wasn't even ductwork under the cabinet, but rather the vent exhausted into the frame under the cabinets, which then vented out the kick-plate.
My system would push out gas fired hot air in winter, and integrated AC in summer. He had a HRV.
No splitting in the cabinets, no peeling of the veneer, no warping of the frames.
A lot of the strength of a wall comes from it being anchored at both the top and bottom. If you only have it anchored at the bottom, your concern that the wall would lean or fail entirely is well-founded. Building a false wall is not a terrible idea, it just needs to be built correctly to handle the expected load. You could also attach directly to the (presumably) concrete block walls using appropriate fasteners and methods.
I would double check that you would even need permits and an inspection. Cabinet installation is not something that usually does, even in basements.
