Probably, at least in principle; I don't remember the code offhand to 
know how easy/difficult this might be.

But my first reaction to the question is to ask whether Unicode 
character blocks are the most useful thing to map. They're rather 
arbitrary, with things like Latin script split up across numerous blocks 
largely due to historical accident.

Mapping the Script property to char classes would seem much more useful, 
IMO.
