Oh, that's simple too. There are filters map and default.

      map_name: "{{ ec2_facts.instances |  map(attribute='tags.Name') | map('default', 'foobar')|list  }}"

That's what I needed! I can manipulate the list like I wanted now! I looked up defaults in ansible and did not see this command. Thanks a lot.
