Answer 1

Am I just going to have two trees of components with a single injector

Yes, you will have two independent root trees. They will be registered under ApplicationRef.views and when ApplicationRef.tick() function will be called Angular will run change detection for both trees. It will be single application and they will share the injector defined for the AppModule.
