Can this be used for replacing an existing GraphqQL implementation gradually ?

Currently, we have a use case where we have a graphql implementation (using spqr library) which we are trying to replace with sping-boot-graphql.

```
@Component
class SpringBootImplementation(
private val executionGraphQlService: ExecutionGraphQlService,
private val graphQlSource: GraphQlSource
) : ServiceProvider { ... }

@Component
class SpqrImplementation(
@Qualifier("restGraphql") private val graphql: GraphQL
) : ServiceProvider { ... }

// create a runtimeGraph by stitching service providers
val runtimeGraph = SchemaStitcher.newBuilder()
.service(springBootImplementation)
.service(spqrImplementation)
.build()
.stitchGraph()

graphQLOrchestrator = GraphQLOrchestrator.newOrchestrator()
.runtimeGraph(runtimeGraph).build()
```

Is this possible? Or am I missing something? Let's say the same type is present in both implementations, including the same exact queries. In SpringBootImplementation we will add gradually and replace existing implementations from SpqrImplementation
