Is anyone aware of a rank-based, non-paired test such as the Krustal-Wallis,
that can accommodate weights?
You don't say what sort of weights, but basically, no.
Whether you have precision weights or sampling weights, the test will no
longer be distribution-free.
Alternatively, would it make sense to simulate a dataset by duplicating
observations in proportion to their weight, and then using the Krustal-Wallis
test?
No.
