Yeah, I don't know how useful it would be for this specific application just due to the architecture differences. Just for a off-the-grid file share, a ESP32 with a SD card wired up to it is still a lot less power hungry than the Raspberry Pi. Even under full load with the radios powered up, you're looking at like 0.75W, and when you're not actively transferring anything you can go into any of the various sleep modes and hit 0.05W (modem sleep), 0.0025W (light sleep) or 0.00003W (deep sleep). That's an order of magnitude difference versus a Raspberry Pi. You can easily power that esp32 pretty much indefinitely with like... a 4x6in PV panel. It's a fun thought experiment on where you could toss a little 4x6 inch panel that has wifi and a 32GB microsd card you can access via wifi or something. But yeah, doesn't really make much sense to me in this use case.
