Ansible combine 'setup' output with task output to JSON

I currently gather facts about all my hosts using this command:

 ansible all -m setup --tree out

This creates a file for each host in the directory out with all the ansible variables in JSON format. Very useful.

However, my hosts consist of a lot of KVM hosts, so I want to add the output of virt / list_vms to each output.

I created a small playbook:

hosts: myhost

tasks:
  - name: VM list checker
    virt:
        name: list the VMs
        command: list_vms

I run this playbook like this:

ansible-playbook -v status.playbook.yml -s

I would like the output to be in JSON format, preferably combining the facts and the output of the list_vms.

How can I create a similar layout (one JSON per host in the out directory?) with the combined information?

Using the input from @KonstantinSuvorov I came up with this:

---
- hosts: kvm_hosts
  gather_facts: no
  tasks:
    - setup:
      register: setup_res
    - virt: "command=list_vms"
      register: cmd_res
    - copy:
        content: "{{ setup_res | combine(cmd_res) | to_nice_json }}"
        dest: /tmp/out/{{ inventory_hostname }}.json
      delegate_to: localhost

You can do something like this:

---
- hosts: all
  gather_facts: no
  tasks:
    - setup:
      register: setup_res
    - command: echo ok
      register: cmd_res
    - file:
        path: /tmp/out/{{ inventory_hostname }}
        state: directory
      delegate_to: localhost
    - copy:
        content: "{{ setup_res | to_nice_json }}"
        dest: /tmp/out/{{ inventory_hostname }}/facts.json
      delegate_to: localhost
    - copy:
        content: "{{ cmd_res | to_nice_json }}"
        dest: /tmp/out/{{ inventory_hostname }}/cmd.json
      delegate_to: localhost

replace command call with virt.
