That's sort of where I was going. However I'd keep the
firmware SD internal as a microSD card. Doing so removes
confusion over which is which albeit at the compromise of
a second user accessible slot.
microSD has become quite cheap and a microSD socket will
add less than US$1 to the BOM cost. The PCB footprint
even including mounted card isn't much greater than a 56
pin TSSOP flash part yet provides the trivial upgrade/replacement
option as above.
