Can't you just use the foo-n suffix trick from the pinctrl etc?

my_nexus: nexus {
   gpio-map = <...>;
   interrupt-map = <...>;
   nexus_i2c0: i2c-bus-0 = <&i2c4>;
   nexus_i2c1: i2c-bus-1 = <&i2c6>;
   nexus_i2c2: i2c-bus-3 = <&i2c8>;
};

&nexus_i2c1 {
     sensor@4c {
          ....
     };
};

Maybe it's not as elegant but I think it could work?
