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?
