That is the only scenario that makes sense, as far as I can see. I have a hard time imagining AMD would stack perfectly good 64 MB V-Cache chiplets on top of salvaged 6-core CCDs. They must have built up such an inventory of partially faulty V-Cache chiplets that makes salvaging them worthwhile. However, that in turn means that the rumoured 12-core 5900X3D will most probably have two salvaged V-Cache chiplets stacked on top of two salvaged 6-core CCDs, for a total of 32 + 32 = 64 MB of V-Cache, and a total of 128 MB of L3 cache (64 MB on CCDs + 64 MB on V-Cache chiplets) — assuming all the salvaged V-Cache chiplets have half the capacity (i.e. 32 MB).Note that 5600X3D is reported/rumored to only add 32MB, so only half of the v cache. If true it's pretty much the dumping ground for all X3D dies where parts of the v cache broke, but at least half of it was still salvageable.
