In my mind, this mixes up different concepts:
Putting it all together runs the risk of producing some kind of franken-core, not properly compatible with m5 concepts, but also not ideal as a basic robot board
I take your point.
It's driven by interest from @ottodiy. If we can support their use case well then they might help with the distribution/ development of the board. I guess I hope it could be a board that sees you through a robotics journey
1) Get a Rosmo/ Otto wheeled moving about on continuous micro servo & Blockly 2) Invest a bit more & make a walking Otto 3) invest a bit more and plug in some grove stuff 4) Invest a bit more and add an official M5 stack motor driver 5) Invest a bit more Add a RosmoESC(s) to give better motor control 6) Invest a bit more and get a proto board, do some soldering 7) Fry the board with your dodgy soldering, get a proper M5 core instead :)
Ah, I see! I'll make the observation that Ottos head looks a bit like an m5 stack in shape... :-)

Very rough sketch of CERN licenced ESP32 board in 5cm x 5cm M5stack dimensions.
Use cases might include:
Rosmo https://rosmo.io
Rosmo with micro servo Driven just by Open Core and 2x continuous rotation micro servo instead of BLDC. These could fit in the existing BLDC socket with a 3d printed adaptor

Otto Ninja is 4cm x 4cm internally
Notes Nice 'snap' proto board here
