Default Choke on 1 channel for 2 motors or 2 kill switches?

Odd question, I'm almost done with my 155in F7F Tigercat, but struggling with wiring ideals.

I'm running 2 DLE 120 4T (4 cly/ motors), I have a servo for each motor on choke (sbus Futaba),

I have had several twins but they all had a pull rod for choke but as this has 2 carbs per motor it would be a pain.

I'm using a Futaba 32MZ and the 18 channel Power expander/DLPH-1 will have 6 door servos, 2 choke, 1 nose stearing, 2 rpm sensor, 2 temp sensors on SBus.

So would / can you put each choke servo on one 3 position switch with middle position being no choke, up choke one motor 1 choked, down motor 2 choke, then use electric kill switch to kill both at same time if needed for gear up landing?

Concern is starting if both on one switch, I would need to turn on choke, flip one until it pops, stop flip other until it pops, then flip choke and pray both start and don't need re choked as it will kill running motor.

​​​​​​The 32MZ has 2 switches on very back of transmitter, not easy to flip in flight, so if I put each choke on it own rear switch, and electric kill on 1 main switch, this would work better?

Could 1 electric kill switch power 4 ignition modules? (2 per motor 4 cly) or would I need 2 kill switches?
