Distributed schemas merge

[kAlexPodles]

Hello,
Is it possible to merge distributed schemas of the same type? For example, there is a type User which lived in a different services A, B, C and the goal is to merge the query results from every source.

Service A
type User {
  id: String!
  firstName: String
}

Service B
type User {
  id: String!
  relationshipStatus: RelationStatus!
  hasChildren: Boolean!
}

Service C
type User {
  id: String!
  street: String!
}

and receive after merge

type User {
  id: String!
  firstName: String
  relationshipStatus: RelationStatus!
  hasChildren: Boolean!
  street: String!
}

This is possible with a similar to stitching https://github.com/ChilliCream/hotchocolate-examples/tree/master/misc/Stitching approach, but in this case User schema should be unique in every service in order not to be overridden during the mege.

I was wondering is there is another way for current scenario?
