Controlling the camera by a MCU

I am working at a motorized tripod for panoramas. I would like to use  CHDK camera for now, which will be controlled by the thing that drives the motors for the tripod.
The most obvious solution would be a Raspberry Pi Zero W, which would drive the motors using the GPIOs and talk to the camera by the USB PTP interface.
Another solution would be to use an ESP32 and talk to the camera by UART (though this requires opening the camera and finding the rx/tx pads).
How about WiFi? ESP32 has wifi, can CHDK work by wifi? I've seen some older threads about PTP over WiFi, but not sure what is the current status yet.

I would rather use an ESP32 than a Raspi (cheaper, less power hungry) but if I have to I can use something else.
