Now add in my 'old' idea: give this boogar a rechargable lithium battery that is shaped like 4 AA batteries; the best of both worlds.
4 AAs produce 4.8V (rechargeable) or 6.0V (alkaline). Lithium batteries produce 3.7V (1 cell) or 7.4V (2 cells).
How are you going to handle the different voltages and how are you going to estimate remaining capacity when you have different voltages and different discharge characteristics?
Well that's pretty easy. You design it that way. Take it for granted that 4 double a's are not going to last as long but how it gets done is easy, for Canon's engineers.
Also to note a lithium the size of 4 AA's would be bigger and give it a higher capacity as well. They could design the voltage of the Lithium battery to match that of 4 AA's and then it would be a natural.
