Yeah a 30 round stick mag for the FAL is a must. Those were fielded in quite a few conflicts around the world.
As far as I know, 5.45 "drum mags" have not been developed aside from the consumer "Beta-C" model in the United States. These "casket" magazines hold 60 rounds of 5.45 ammunition. I think they would be a good replacement for the drum mags on 5.45 AKs.
