Just because the coastline follows MLW as it goes around the coast doesn't mean it needs to follow every tidal waterway inland. That doesn't follow at all.
To achieve what you want you would need to add yet another way inside of the riverbank and intertidal areas which seems like a fair bit of effort to do for every river for no real benefit to map users whatsoever. Then you need to get it all to render right where you have tidal mud banks, etc. in the centre of the river.
