While that does seem like a nice idea, I highly doubt it'll materialize because of the sheer cost of ロケハン(location hunting). Atleast some of the key staff would need to visit every prefecture in Japan to take photos, gather local material(a lot of which might not exist online), which would cost time and money; both things the anime industry lacks.

Collaboration between different studios is also not viable because barring some exceptions (PA Works in Toyama, Kyoto Animation in Kyoto/Nara), almost all the studios are concentrated in Western Tokyo.

Unless, if the anime was crowdfunded. Maybe.

(I don't currently work in the industry; I'm just voicing my personal opinion.)
