It could still be a viable link if the second tunnel in the train station with lift access to the platforms was reconfigured as a through-route. The ticket gates could be located in the lift door recesses instead of either end of the tunnel. I think there would still be space for wheel chairs/prams/luggage etc, although it is not ideal.
