There is a bit of relevance; however, you are also touching the topic of “personal identity” which is too undeveloped yet to go in.

As a side note, it seems likely that bridge hypotheses can be built for some other entity (other than self), but there are inevitably less constraints on validity of them and, thus, less concentration of probability over them, and, thus, multiple hypotheses can easily be comparably plausible, basically making the situation into “multiple [possibly overlapping or non-overlapping] experiencing entities in any brain”.

The ethical implications can be funny but, at this point, are all too far-fetched.
