Maybe you can elaborate on what it is you're willing/able to change and 
not change.  Use of sudo itself requires changes (editing of the sudoers 
file).  If you've already done this, then I don't see why you can't use 
the NOPASSWD keyword in it (though I wouldn't recommend it). 
Alternatively you can pass the password to sudo on the command line via 
echo <password> | sudo -S <command>
