I think it won't work.

(1) One entry can contain an ensemble of many models. 4PTH has 250
models and each atom has occupancy 0.004. It's similar to alternative
locations, but taken to extremes.

(2) One entry can contain a single model and multiple datasets. 5RKZ
has 1500+ datasets from crystals soaked with different compounds. You
can concatenate reflection mmCIF files, but only the first block is
used for validation. I suppose all the models were similar, so one can
obtain them by refining the single deposited model to each dataset.

I don't think you can meaningfully deposit multiple datasets with
corresponding models in a single entry. (2) is probably the closest to
what you want.

Best wishes,
Marcin
