Shouldn't be a problem. There's no overhang from the platform if mounted on either roof, so it shouldn't impact another platform on the opposite roof.
Re: the Backbone system. In case others are interested, I enquired about whether or not there were any distinct advantages with the Backbone compared to the ordinary RLT600 quick-release mounts. This was Rhino's answer:
The backbone mounting system has been designed to have a sleeker profile, to have a higher load rating and to be more aesthetically pleasing than the RLT600 setups. As the load rating is most often determined by the roof of the vehicle and not by our products the load rating is limited to 100kgs for both options for the Hilux.
The main differences to consider for your particular vehicle are 1) if you prefer the look of the backbone mounting system, 2) If height restrictions are something of an issue for you, you may wish to consider the RLT600 setup as this is a quick release leg, allowing you to take your platform on and off of the vehicle with comparable ease, whereas the backbone is fixed, 3) While you should expect some increase in wind noise when adding anything to your vehicles roof, the Backbone mounting system should be quieter than an RLT600 setup.
