Couldn't you just iterate over a list of data objects, generating a unique
FRB in each loop iteration?

Schematically:

>>> objects = [ds.proj(..., weight_field=None), ds.proj(...
weight_field='density')]
>>>
>>>for obj in objects:
...       frb = obj.to_frb(...)
...       ds_frb = frb.export_dataset(...)
