Good idea. Just implemented very similar thing this past weekend hereWhy the Pi for such ultra-light application? ESP8266 or ESP32(Bluetooth for beacon / Wifi for SSID) do the job with lower consumption.
"All-In-One board" for SSID version based on ESP8266/ESP8285
EDIT:
Board for BT and Wifi based on ESP32 (just a bit expensive / needs step-down converter and definitely a custom firmware)
