Something like the following should work:

setdir() 
 cd "$1"
 export SETDIR_DEFAULT="$1"


my_cd() 
 cd "$1-$SETDIR_DEFAULT-$HOME"

Note that these are functions, not a separate script. You can't do that from a separate script, since it would not be able to affect the parent shell that calls it.

If you really want to override cd (please, don't do that), replace cd with builtin cd.

I know it might be a bit late for the answer, but you might like the idea of CDPATH vaiable. It allows cd to refer to content of directories in this variable from anywhere. Here's an example:

$ mkdir -p test/1,2,3
$ cd test/
$ mkdir 1/a,b,c
$ export CDPATH=/tmp/test/1
$ ls
1 2 3
$ cd a
$ pwd
/tmp/test/1/a
$ cd ~
$ cd b
$ pwd
/tmp/test/1/b

More details from man:

 CDPATH A <colon>-separated list of pathnames 
 that refer to directories. The cd utility 
 shall use this list in its attempt to change 
 the directory, as described in the DESCRIPTION. 
 An empty string in place of a directory 
 pathname represents the current directory. If
 CDPATH is not set, it shall be treated as if 
 it were an empty string.
