Roll over risk and driving dynamics would be a disaster, but car regulations for a long time have required to have enough structural strength to support whole car weight upside down so as to not crush passengers in an accident, this uses that structure otherwise useless to be used during normal operations with battery pack on top,
This also compounds the problem, rooftop battery has to also support to whole car, in accident
Tldr - usable battery will be small, for the loss of driving dynamics

i guess you have to stick it somewhere, but... putting one of the heaviest components high up?

Well, Ford already has a history of SUVs rolling over...
