I don't know of anything but it's a cool idea. A panner is just a bag with a stiff backing board plus mounting hardware. The collapsible bag part is easy, the problem might be getting the stiff backing board to fold up. A DIY option might be to make a concertina folding back board (strips of plastic with duct-tape living hinges?). The mounting hardware could bolt through the plastic strips. When unfolded, the backing board could slip into a sleeve on one side of the bag component.
Once upon a time a client came to me wanting to develop a fold-out tray that attached permanently on the side of your rack, so you could fold it out and strap your handbag/shopping bag to it if needed.
Another option could be a bikepacking bag, my old Bikepack.pl seatpack isn't as rigid as some others (although I see they have changed the design since I bought it) and crumples up to the size of a small melon. It's maybe 12 litres, so pretty small compared to a pannier, though.
