Forgive my ignorance, but what happens if you simply re-project the data to the native raster's projection? I found a tool on directionsmag.com that can do batch re-projecting, if you have multiple files, and have found it extremely useful in the past. If you're curious, here's the link:

When adding in a raster layer to a map window, the map window will reset itself to the raster images projection. This is what causes the distortion. It is actually not a distortion as far as the points are concerned, it is a matter of the view. Longitude, Latitude datum files really cause serious display issues with rasters as well because they do not points that translate well geographically. If you know what raster image is registered as, there is a workaround for generating a map view without getting the distortion. Set up your map window the way you want it. Add in the raster layer and turn off the display. Set the map options, display to display in Long, Lat, and then you can turn the raster layer back on. However, if you need to zoom in or out, you will need to turn the display on the raster back off again. For whatever reason this worked for me, but you may need to find out what your file projections are before you can do anything, as to get a really good raster projection without a shift, you need to register the layer in just the right projection.
