Will there be a new Bus Eireann express route 12 Limerick to Dublin?

Since they are making amendments to route 20 making the 20X and also with the 51X from Limerick to Galway wouldn't it make sense to do the same with the Limerick to Dublin route with a direct/non stop or limited drop off every second hour. Then would be very beneficial especially on a Sunday when most passengers will be travelling to Dublin and if there is a good demand an extra bus could go up. I travel up most Sunday evenings on the 18.30 service and it is shocking to see the amount of people that are left behind in places such as Nenagh, Portlaoise, Roscrea because the bus is full. This used never happen but since the 16.30 Non stop service from West Clare to Dublin on a Sunday was cancelled this has become a common occurrance. Still even at that why go through these places and leave people behind because the bus is full. Wouldn't it make sense to have a full service on one hour and then maybe a limited or non stop service on the second hour?
