yes, that is a good idea. There are several samples/examples out there.
A good starting point is:
> - Studying the power consumption (matlab simulation)
that might be a little more difficult because there are no models of the chips that are in use (and they tend to be non-linear and depend on software activities). But your students could identify the power tree and try to make assumptions about DC/DC converters, LDOs and power consumers (chips).

this should be doable if you 3D print your battery covers yourself. There is an internal "AC" input on the RS232 console connector (although AC is quite wrong - it is a 5V DC charger input).

Most information is available in the manual incl. a block diagram and the complete schematics.

Yes, please. This mailing list would be a nice place to write questions.
