Personally I would only really do it this way if the release is a “collection” of separate releases. See this release for example:
The first two mediums make up an album, so the tracks are labelled A#, B#, C#, D#. The third medium was originally a separate release which was “bundled” with the album, and so the tracks are labelled A#, B#.
However I don’t think anyone would find your proposal unacceptable given you could reasonably argue artist intent based on the labels.
