Before 2000 I think Philipps had a mobile with standard
batteries. The radius of the AA are quite big - but when
I would like this idea, too.

You have calculate mAh*V/volume

But you bring me to the idea that it would be nice
to have a small capcitor parallel to the baterie
have 20-30 seconds to excange the SIM or the battery
without switching of the device - maybe just put it into
sleep mode to reduce power consumtion.
