There is no way to ‘[union](https://community.fibery.io/t/how-to-union-two-list-fields-in-the-same-database/2467)’ two collection fields using a formula.  
It may be possible to create a collection field that gets updated when each of the feeder fields changes using a set of automations (linked and unlinked triggers) but it will be ugly, and users can potentially edit such a field.
