An imaginary Palace construct

I’m wondering about the practicality of an invented/imaginary Memory Palace as opposed to a real structure, particularly with regards to a very simple imaginary construct like this:

That idea appeals for a number of reasons - neat & clean, symmetric, uncluttered, configurable and expandable. I’m attracted to the idea of assigning my 12 acupuncture meridians to the 8 bookcases and 4 tables, then storing supplementary information on the shelves.

But I worry about the “recallability” of the stored information in an imaginary Palace.

There was some discussion about this, including an update from Andrew himself, on my post
