I have been thinking about using a fireball release but gave up as I did not want to buy the QR + cab depower ( prefer long throw )
Seems like the factory parts are held together by a palstic thread ? or is there a metal piece too ?
Your mod looks good but how to figure out if strong enough over time, I am not sure at all after you drill the plastic.
what is the diameter of the safety line that can pass through the metal "funnel" of the QR ?
The cab depower has a split PU tube to protect the thin ( 2mm I think ) safety line, but if you use the same exposed it will get worn quickly.
this guy made a mod to use a firebball for a sliding rope harness, if that can bbe of any use ( page 4 - 5 )
