Another thing would be that the read-only transaction still needs a
snapshot, and whatever transaction ID it uses will have been used by
the server also.
I think the visibility issue may be solvable as long as the transaction
ID on the slave doesn't pass the VACUUM horizon of the server. But it
would require careful studying of the WAL write order to be confident
it would actually work.
Have a nice day,
