Modding the Voyager so the BT Microphone can be used seperatly.

I found these guides and was hoping for help. I have a couple of Voyagers laying around. I now use IEM’s for better audio but have yet to find anything that rivals the Voyagers noise-cancelling microphone. Is it possible to hack the voyager so that I could use just the microphone and noise cancelling circuitry alone? Preferably adding an MMCX connector onto the Voyager and possibly hacking a FiiO RC-BT so that I could plug the Voyager mic into it via an MMCX cable. I love my IEM’s and I love the Voyager for calls, I hate having to rip these out of my ears so that I can go from one to the other. My hope is that someone will know how to adapt the Voyager so that I can use the moise cancelling mic with a pair of IEM’s simultaneously. Any guidence would be helpful.
