I might start experimenting with an extension to support this in OpenStreetPad.  I think what I'd go for as a first try would be something along the lines of these properties:

There is the pattern-image property [1] in JOSM which mimics Mapnik's 
LinePatternSymbolizer.

I suppose your idea is similar, but with the image centered at the line 
and not attached to it.
