@ludicroissant, as far as I'm aware this isn't supported. If it is technically possible - there aren't development tools in place to provide examples or a starting point. The watchman protocol is specifically signed for low-latency communication and employs things like advanced compression methodology to ensure that the entire tracking system is as responsive and accurate as possible; having these dedicated radios take on additional tasks could impact the UX.
An simpler and likely more robust approach to this would be to use a separate bluetooth radio for additional controller mods rather than trying to piggyback off of the controler's radios.
