Erm.... the decorating (and several other things) got put to one side a bit...
He said, guiltily.

48mm x 50mm using a standard Pico and no SMD parts (it's the usual uSD module with its own pullups and supply decoupling capacitor that I've used previously). The GPIO header is identical.

Slight changes:
Power is via VSYS rather than VBUS if powered from a serial port. GP22 is via a "buttons enable" link rather than hard wired on the pcb.

Decided it was a little plump, so some slimming exercises have brought it down to a lithe 43mm x 50mm.
