How to consume a dead letter queue in AWS SQS using Justsaying

Question

I'm working with SQS in my application. I have the following configuration.

justSaying
        .WithSqsTopicSubscriber()
        .IntoQueue(_busNamingConvention.QueueName())
        .ConfigureSubscriptionWith(x =>
        {
            x.VisibilityTimeoutSeconds = 60;
            x.RetryCountBeforeSendingToErrorQueue = 3;
        })
        .WithMessageHandler<MyMessage>(_handlerResolver)
        .WithSqsMessagePublisher<MyMessage>(config => config.QueueName = _busNamingConvention.QueueName());

So, there will be 3 re-attempts before the messages gets to Dead Letter Queue. I want to consume this dead letter queue and process the message separately. In essence, I want to create a handler to deal with the messages in the DLQ.

I'm not sure if this is possible or SQS is not intended to be used this way. Please post if this is possible and if yes, is it okay to do this or is this an anti pattern.
