I thought you might be interested about this. I've been recently working on this project, the PCB design was made by another Team member and I worked on the firmware, it's based on Zephyr and running multiple protocols. This was mainly designed for Thread using the openthread stack. The nice thing is that once openthread is up and running you simply get a udp socket on which it's possible to send json that directly talks to an application. Despite the standard networking stack, this Tag has astonishing low power with sleep current of only 3.19 uA. I also tried some experimental custom radio protocols on it like the simple mesh, so if anyone is interested to have MySensors running on it I'd be happy to help.

Do I understand correctly, that you are planning to port MySensors to Zephyr OS?
