Dissolve all adjacent pairs of polygons in a shapefile?

My apologies in advance if I get the terminology wrong or am asking a really dumb question - am learning arcgis for a class.

I have a census boundary file of school districts in a state.  I'm looking for a way to dissolve or merge all adjacent pairs of polygons in this shapefile - I am interested in the shape of every hypothetical merger of two districts. 

I was able to use cmaene's "Find Adjacent and Neighboring Polygons" tool http://resources.arcgis.com/gallery/file/Geoprocessing-Model-and-Script-Tool-Gallery/details?entryID=50F58FCF-1422-2418-884B-A053393CEF92 to generate a csv with a record for each shape ID and fields for the shape ID of every adjacent polygon. 

EDIT: I should probably make it clear that since there are many, many different ways to group the layer of school districts into pairs of adjacent polygons, I don't think the output for this project could be in a single layer, but I don't know what other formats are possible. 

How might I approach this problem? Do I need to learn some scripting?

Thanks in advance for any help you can provide.
