It seems like something easily could be done for this. The base seems to be that for every point a unit has there is 5 food in a quick fight. So a battle that requires 75 points to fight will give about 375 for food. And if you use all 3 energy, about 1100.
Similarly it takes about 5 unit points to get one supply box, so a 2000 point battle yields 400 supplies. What the Dee's could do is add have a "qf all food" or "qf all supplies" then add up a players remaining unit points giving weight of 1, 2 or 3 for remaining energy per unit and then use that total to give food or supplies. And the exhaust all the units. Also there would be no other troopers just the food/supplies Perhaps 1 part in 100 for gxp. Very easily to implement
EDIT: at more difficult boards the payout is closer to one food for two points. Obviously the Deb's couldn't set the number where they wanted but this is a framework for how easy it would be to just convert all units points times energy into food or supplies
