You could in principle (schema is the same), but then you have two publishers reading from the same db.
The APEL publisher keeps track of records it has already published (by a timestamp in one of the tables). So the first publisher (let's say the RGMA one) starts running, grabs all the records that haven't been published and sends them via RGMA. Then, the second publisher won't consider those records (as they are marked as published) and will grab and publish a different set of records.
Running two publishers from the same db won't necessarily create problems, but unless you do some manual tweaking in the db, the publishers won't be publishing the same set of records, which makes it useless as a testing exercise...
Cheers,
Cristina
