There was a site posted here a couple of years ago where you could select an area in OpenStreetMaps and it be would stylize and carve it into a piece of wood using a CNC machine and send to you.

Why not use vector data from OSM?
Or use a pre-rendered map tiles and "just" replace the font: http://maps.stamen.com/toner-lite
- Do some edge detection, extract vector paths from those instead of just a bitmap, have a plotter with ink pen, plot!
- ???,
- profit?
Nope; Google Maps has had april fools' projects a few times where they do something similar, like their 8 bit version: https://youtu.be/rznYifPHxDg
The difference between doing it and doing it well is huge, but not unsurmountable.
It's worth a shot!
Maybe not.
