I think so is not any problem to pass binary data already. Text type "text"
and binary type "bytea" is internally very similar.

But the message doesn't any info about type, so it should be ensure so
clients understand to message and takes data in binary format.

You can overwrite pg_notify function for bytea format.

Is not possible to use NOTIFY with binary data, because this statement
doesn't allow parametrization
