Is it possible to enqueue some Sidekiq workers into an external redis queue?

I have a Rails app A with its own sidekiq and redis server. We are in the process of merging another app B into app A. App B also has its own sidekiq and redis server.

As an intermediary step for the merge, I have migrated the Sidekiq workers from app B into app A. But what I want is instead of adding the necessary queues to app A's sidekiq, I would like to send these new workers to app B's redis queue to be processed on app B's sidekiq.

Is this possible?
