That isn’t even a terrible idea - with that many conductors, you should be able to carry tens of amps. Use two for “Data” (detecting charger) and you’ve got… 21 positive and 21 negative. I’d not be surprised to see that hit 100W without catching fire.
I think a standard IDE connector would do just fine
The pro move there would be to physically modify it so that the power is actually going through the ribbon cable. So bulky, yet so thin!
