supply production during combat? possible?

I have a idea that would work if there is a way to make a quantum reactor create supplies during combat. Have for a long time wanted to make a battletech mod. And thought of a way to make "heat sinks" out of quantum reactors if they worked in combat. My other thought was to make extreme long range gun with zero damage, but generates supplies when fired. Could use some input.

For those that don't know battletech. All units in battletech from mechs to battleships have heatsinks. When you fire weapons you gain heat. Energy create lots of heat, but use no ammo. While balistic weapons create little heat and use lots of ammo. If the heat gets too high it shuts down the unit. much like being out of supplies in SEV
