Is there an implementation of Openstreetmap that closely mimics the appearance of 1:25k OS Explorer or 1:50k OS Landranger maps? By "mimicking the appearnace" I mean same colour scheme, same POI symbols, same typography and labeling conventions, contour lines, etc.
If the answer to 1. a is "no", is it possible to create such an implementation? What might be a good resource to learn how to do so?
Like many Brits, I grew up with paper OS maps and am still more comfortable reading them than a style such as that used at http://www.opentopomap.org/
