Stobart did actually apply for a coach licence to run such a service in 2016. Instead they contracted it out to Kings Ferry coaches which operated under the National Express brand for a couple of months.
I think the main reason why that coach service was so short lived was simply because very few people used it. Why? Because they didn't know it existed. It was difficult even to obtain details of the service at SEN itself: you had to ask at the Moneycorp kiosk and there was no signage. If they were to run a new service (which I very much doubt they will) it would need wide promotion to include emails from the airlines notifying affected passengers at the time of booking that such a service existed. If you don't put that information in front of your customers they're unlikely to find out about it and include it in their travel plans.It would need some joined-up thinking to be employed which doesn't always seem SEN's strong point.
