Create vector grid with diagonal connections

Hello all,

I am trying to convert a raster to a vector line grid for use in building a network dataset. The standard "raster to polyline" tool produces a grid with lines along the edges of each raster cell, but I also need diagonal connections across each cell in order for the network processing to work correctly.

One possible solution I considered, if it is not possible to directly convert a raster to a grid with these properties, is to create a "template" line grid, convert the raster to a polygon, and spatial-join the grid to the polygon so that each line in the grid picks up the correct attributes from the raster. Unfortunately I haven't found a way to create a "template" grid with diagonal connections.

I am aware that I can use cost path analysis to perform route-finding functions in the raster domain, but for this particular function I need to work within the vector domain.

Thank you very much for your help.
