Its possible, if you can get the source code for passwd.
Change it according to your needs, compile it, name it a different name, eg mypasswd, then call it from your script.

That would be overkill, interacting with passwd is one of the most common usages of expect.

Just google "expect spawn passwd" and you'll find tons of examples.
