I believe that a DIAS could probably be manufactured from an MRE spoon so long as it can be bent and hold shape, which would allow you to convert any(?) semi on the platform to fully auto, though for models which fire a larger cartridge the dimensions would probably be different. I haven't seen any examples of a DIAS for an AR-9, -10, or -12.
I had an armorer tell me you could modify most semi-autos to be fully auto with an MRE spoon.
