They should take a leaf out of the book of the Scandi's at Central. I have been to a few stations where the outer walls are bare rock and they have cleaned them up/sealed them and project all things Scandinavian onto them - so mainly calming trees. You could have a lot of fun with that in a creative and historic city like Liverpool.
The trouble with Central is that the roof leaks like a sieve so you need the "false ceiling" to stop it dripping on people. Without that you could pressure-wash it all to get the muck off and then mood-light it, to make it look more like James St's semi-disused platform or the Haagse Tramtunnel rather than just a boring 1980s-like melamine-panelled hole. Even concrete can look nice with the right lighting.
