Bluetooth and 8mm simultaneous

Ok so specific set of questions…

As an airline pilot, i would love to be able to use these headphones while flying.

So the aircraft uses one 1/4in plug for headphones audio and one slight different size for the mic.

Can i

  1. Use bluetooth audio while also using the 8mm audio to monitor the radios when im not the pilot in charge so to speak.

  2. It seems like the easiest mic solution would be a 3rd party external mic like an antlion?
