Surf SOHO and Max Transit Duo

I have a Surf SOHO MK 3 installed on my boat with a wireless and hard wired network for all my navigation equipment, PC and wireless devices. Using a Mikrotik Groove A for longer distance WAN access and a Verizon USB LTE hotspot. Looking for a more consistent solution to be able to do live web conferencing when on the move. Is it possible to keep the Surf SOHO setup and add a devise such as the Max Transit Duo Cat 12 with appropriate antennas to be able to set up two LTE lan connections as well as Wifi as WAN. Is there a better solution?
