That's a nice theory, but largely unworkable as it is generally not possible to discover what roads are "C" roads, at least not from any copyright free source. In fact as far as I can tell each council has it's own referencing system for roads below B roads - some have C, some have C and D, some have U, and so on. I normally just use tertiary for roads which are not A/B but are significant through roads of some sort. Milton Keynes is a special case though because of the grid structured nature of the town, which a special distinction between the grid roads which are intended as distributor roads and internal roads in each block which are only intended for getting in to/out of that block from the nearest grid road.
