The funny thing is it already sort of exists: the E-Book FeatherWing will accept a Feather RP2040, and may even use the same pin assignments as the M4 Express! Would love to do an update though, to bring in this simpler MicroSD and castellated EPD driver. https://makezine.com/projects/the-open-book-and-the-e-book-featherwing/
