I don't mean that you'll plug the same number into the battery box - I mean
that over a year of use, the TOTAL number of batteries that you'll consume
will be about the same.

Yes - but in this hypothetical nightmarish world, there would be no single
motors to buy, no official cables to connect things with, etc.
In short, there would be no point in hacking into "the box". You might just
as well go completely non-standard/non-Lego and just build a suitable computer
with whatever motors you fancy.
You might use Lego for the *structure* of the robot - but all of the electronics
might as well be fully custom.

We live in hope (but not much hope!)
