This is what I was thinking , pico rev 1.5 or pico pro if you will :)
build in watch crystal
micro usb instead of type A
replace 0.05 GPIO pins with extra 0.1 GPIO pins (0.05 are hard to access unless you surface mount unpinned pico ). I would definitely back it on Kickstarter ;)
On the other hand a low cost very basic board would be an affordable option for people with limited budgets
