I think this is a great educational DIY project, but of a little value
in practice.

Aside of squeezing everything into a small case you have to care about
power consumption, lots of little bugs (especially USB host related
ones) and the closed blobs needed to boot. You'd need a lot of work to
make it really usable as a daily phone - however, getting it to a
"somewhat working" state is indeed pretty fast.

It's a perfect topic for some workshops though - "make your own
smartphone"! Augmented with some programming lessons (Python?) and
using FSO API to "write your own smartphone OS" with whatever
graphical toolkit you'd find suitable for the audience, it could
probably be a perfect activity for some extracurricular activity
groups in schools :)
