Wanted to post a possible alternate solution by getting a list of variables that match a pattern, then you can just process all those variables, sorta manual merge.

The following code block gives an example of pulling all variables that match a specific pattern and looping. you could set a new fact with them merged, or simply process them all individually.

- name: "debug2"   debug:
    msg: "value is: {{ lookup('vars', item) }} "   
  loop: "{{ hostvars[inventory_hostname] | select('match', '^linux_hosts_entries') |list  }}"

see the following post for further details.
