Matthew, I find servo based speed controllers seem like a good idea (and cheep) but 
I think you`ll find rather hard to build and maintain,If your confident you can 
build your 2 speed mag esc then go for it,but servos get jumpy, 
just when you dont want then to, 
The other point to make is the torque at 12v will be lower than at 24v not just the 
speed.
not trying to put you off, just want to point out the pit falls.

here is an idea for a 2 speed mag style control
 
the F1 and R1 switches can be used to operate the mag relays as normal and the F2 and R2 switches can control a relay that switches the motor supply for each motor between 12 and 24v.
 
2 of these are still needed one for each motor
 
also if you have a transmitter with built in mixing you can use it on one joystick as with the tri-pact control
