Your camera records in 16/48k, based on the info I could find.
Ideally, you would demux the audio stream from the video, then edit that as you would any other 16/48 audio recording.
The downsampling in your audio source was done in the transfer to the R-09.

As long as the lineage is properly stated, it would be allowable IMO.
Not really any different than a DAT > CDR > EAC lineage method, maybe actually a step better due to the lack of the EAC extraction.
