Elevation interpolation along a (sewer) line

Hi smart GIS folks,

 

Here's what I want to do.  I have a vector sewer line feature class that contaings a field for the high invert elevation and one for the low invert elevation.  I can turn them into a raster no problem but what I can't figure out is how to interpolate between the two ends (high and low) and assign the elevations to the raster cells.

 

Ultimately what I need to do is compare the sewer line raster to an elevation raster to determine likely overflow points in the event of a backed up line.  My thought is it would be similar to creating a reservoir with a blockage being the dam.

 

I hope I articulated my question sufficently.

 

Any thought??

 

Thanks!
