One problem is that basic movement commands are in C, not in Lisp.

Another problem may be advise on functions - the "shift" handling
may then be performed too late.

Personally, I like my proposal of just setting a "shift" property
on the relevant commands, and do it by running a shifted-key-hook
in the command loop.  

That method has proven to work excellent with CUA mode!

For one thing, it is trivial for a user to add shift-region support
for new movement commands in an external package - without modifying
the code of that package.
