Multi GoPro 3+ / Tarot gimbal FPV to single ground station

Hi all and apology in advance for lack of detail knowledge.  I know what I want but not sure if possible and if so what the bits I'd need are.  I have 3x GoPro 3+ / Tarot 3DIII gimbal on motor  vehicle. I can get power to the gimbal and the camera for perm connection.  I was wanting to get FPV via 5Ghz back to a single control station (with 5" monitor) so I could independently select which camera I was viewing and for that camera the ability to use a joystick to pan/tilt the camera on the Tarot gimbal.  I hope that makes sense.  Very grateful for any suggestions.
