Use 
  M-x narrow 
or
  M-x narrow_to_region
to confine all edition to the region.

Afterwards restore with 
  M-x widen  
.

Of course it is possible.

The magic variable is 

 Integer_Type `REPLACE_PRESERVE_CASE' == 0  Undocumented

Probabely also CASE_SEARCH (see Help>Describe Variable CASE_SEARCH).

Try playing with them, you can set a variable with evaluate_cmd(), by
default bound to  M-X:

 M-X CASE_SEARCH = 0
 M-X REPLACE_PRESERVE_CASE = 1

[ Advertisement:
  With http://jedmodes.sf.net/mode/hyperhelp/ you can use the function
  set_variable().
]
CASE_SEARCH can also be set with toggle_case_search().
