There is another approach that does not involve a URIResolver at all. 
After changing the location of the imports, just have either a batch 
file or the program itself rewrite the imports section of the stylesheet 
with the current paths, as obtained from the configuration file.  You 
could actually do this each time you run the program.

You could also do it with another xslt stylesheet, for that matter, but 
it would probably be easier to do with a bit of code.
