I believe you would have to get to a sophisticated system like Rugged Radio has and reprogram the radio to FRS channels, if that is possible with their frequencies (probably is) (UHF 462.xxxx MHz) . You are talking about some big bucks (big to me). Alternatively I have two Fodsport motorcycle helmet sets (Amazon) that work VOX and have used a CB with an extension speaker mounted on rear roof bar above my right ear that is easy to hear and grab the microphone to respond when needed. Make sure you want a lot of group chatter in your ear and sharing thoughts with/from your wife shared with all. The Fodsport are bluetooth and can link up to 16 riders together and get about 1/2 mile range and they daisy chain to the whole group if properly set-up. There are also systems by Sena and others reputable companies. Can look and buy some of those at Cycle Gear stores/website. Hope this helps.
