Hoping this could do it:

[stack at instack ~]$ cat yaq.yaml
heat_template_version: 2016-10-14

outputs:
   debug:
     value:
       yaql:
         expression: $.data.l.reduce($1.mergeWith($2))
         data:
           l:
             - "gnocchi_metricd_node_names": ["a0", "a1", "a2"]
               "tripleo_packages_node_names": ["a0", "a1", "a2"]
             - "nova_compute_node_names": ["b0"]
               "tripleo_packages_node_names": ["b0"]


[stack at instack ~]$ heat output-show yaq debug

}
