I'm not sure if that would even be possible, but you won't need an emulator to do that. Citra doesn't even have a Memory Viewer. You can do RAM dumps with NTR CFW, but you will need a N3DS if you want to use it on Sun/Moon. Gateway would also be an alternative but I don't know how and if that would work with SM.
Anyway there's probably only a minimal amount of data stored for enemy Pokemon, so no OT, TID, etc. You would have to recreate it based on this data.
