Yes, the ign switch powers bus 15.
I disagree with you that bus 15 is overloaded.
Moving from d15 to d23 does not put any more load on that bus, it just moves the coil feed and the crankcase vent heater to a physically larger connector. And it’s just one splice into the existing wiring.
Making a jumper from a8 to the wire coming off d15 is as you said, redundant.
It works for you, and what I did ( 19 years ago now) works for me .
I’ll reiterate. I do not think the 15 bus in the fuse panel is overloaded and needs to be sistered.

Back in the air cooled days the back up lights where actually tapped off the ignition coil with an inline fuse. So was the heater fan from 72 on in the busses. As a small upgrade the crankcase vent heater can be moved to the O2 sensor feed which is actually connected to the power for fuel pump-injectors.

This does 2 things, feeds from the switch to the suff that matters and for the other stuff that feeds off track path 15 in the fuse box you now have redundancy. Moving the wire to D23 still leaves A8 as the next week spot and still leaves the possibility of failure on the bus within the fuse box. The path thorough the fuse box is a weak link for number of circuits including the stater solenoid.
