It would theoretically be possible to merge these routes.
I don’t think Danny is going to be your person for this as whilst he’s very good at merging routes, to my knowledge he can only merge routes with the same origin point whereas SpeedyPete is the king of merging routes with different origin points.
Aside from all this though is the fact that merges are a LOT of work when you’re dealing with different origins. For example it would’ve, in retrospect, been easier and less work to build the entire ECML from scratch rather than merge them together.
