All right. Here you are a complete example. Just tested it.
Sorry for the long email.

CREATE TYPE type_customer AS
(id integer,
cust_name character varying(100),
email character varying(100));

CREATE TYPE type_supercustomer AS
(cus_data type_customer,
superpower character varying);

CREATE TABLE public.table_customer
(
id serial NOT NULL,
cust_name character varying(100) NOT NULL,
email character varying(100) NOT NULL,
PRIMARY KEY (id)
)
WITH (OIDS = FALSE);

CREATE TABLE public.table_supercustomer
(
superpower character varying(100) NOT NULL
)
INHERITS (table_customer)
WITH (OIDS = FALSE);
ALTER TABLE table_supercustomer ADD PRIMARY KEY (id);

CREATE OR REPLACE FUNCTION function_read_supercustomer()
RETURNS SETOF type_supercustomer AS
$BODY$
DECLARE
retset type_supercustomer;
BEGIN
FOR retset IN
SELECT (id, cust_name, email), superpower
FROM table_supercustomer
LOOP
retset.superpower := initcap(retset.superpower);--works
(retset.cus_data).email = 'anything you want';--does not work
RETURN NEXT retset;
END LOOP;
END;
