Basically, the KiCAD schematics will have to be updated (which should have been done anyways :S), and both will have to be re-soldered in order to allow for usage of the chip's UART coms.
TWI would have been nice, sure, but since the ESP-01 has a fitting hardware implementation that supports receiving and sending ... This works better.
