Seems like you could rewire the stock electronics to work with the Jack and FCU, just trace down what goes where (semi/auto/trigger), and wire it up to the FCU. Afaik FCU needs a closed circuit for full auto and open for semi so the stock switch is usable. So is the trigger. You'd have to be careful not to send 7.4V to signal wires while keeping the stock electronics tho… Would need to have that thing in my hands with a multimeter to check what goes where. Since the mag has it's own switch you could just hot wire 7.4V directly to the mag and to the engine FCU and use all the stock electronics just for the FCU signals (with no power to them).
edit: btw it looks like a really fun project edit2: somehow skipped the battery compartment part…deleted stupidity out of the comment
edit3: does the mag feed while you fire or is priming it the only way? If it feeds while you fire it you'd need to take the trigger contact, add a mosfet to it and wire it to the mag contacts so that when you pull the trigger it feeds but there's no voltage on the trigger itself so that it can be also used for the FCU.
Could try pmma tubing can get 10mm (8mm internal) for pc water cooling its usually nicer to work with and doesn't kink as much much as the others if you use a silicon insert shouldn't kink at all

I wouldn't 3d print that feed tube. I would use the existing tube and get a 6mm ID tube and just shove it in.
James, use a feed spring for a 249 box mag 👍 also talk to polarstar about using it in a gel blaster 🤞
