Rather than going by camera, wifi SD cards were a lot of fun back in the day. I wonder how much you can do with the modern smaller form factor of modern SD cards. Could pair it up with an app on your phone via Bluetooth etc to retrofit more features on. Much like an Apple Shortcuts/CloudKit.
Would be a fun retrofuturist experiment to backport fun newer things to old tech with big SD cards.
Sounds like things haven't improved much in the past twenty years based on links like these:
