I never tried - so I can't say for sure.

But even if the structure of chunks is different, the content / payload
is the same (else wget would detect that and re-download from the
start). I see no technical problem here.

Then, chunked transfer makes mostly sense when transferring dynamically
generated content. And that likely means two successive requests will
see two (slightly) different contents.
