can a function have a setof (returned from another function) as input

I'm trying to create a function that will take setof results from various
other functions (they all produce the same output format). Is this possible?
if so how do call it.

ex.
CREATE TYPE emp_t AS (
ID int,
name varchar(10),
age int,
salary real,
start_date date,
city varchar(10),
region char(1)
);

CREATE OR REPLACE FUNCTION func1() RETURNS SETOF emp_t AS $$
DECLARE
v_row emp_t;
BEGIN
FOR v_row in SELECT * from employee
LOOP
RETURN NEXT v_row;
END LOOP;
END;
$$ LANGUAGE plpgsql;

CREATE OR REPLACE FUNCTION func2() RETURNS SETOF emp_t AS $$
DECLARE
v_row emp_t;
BEGIN
FOR v_row in SELECT * from diff_table_or constraints
LOOP
RETURN NEXT v_row;
END LOOP;
END;
$$ LANGUAGE plpgsql;

CREATE OR REPLACE FUNCTION myanalyze(in_t emp_t) RETURNS SETOF <something>
AS $$
DECLARE
v_row emp_t;
BEGIN
FOR v_row in EXECUTE in_t
LOOP
-- do something
RETURN NEXT v_row;
END LOOP;
END;
$$ LANGUAGE plpgsql;

-- so I would like the call to be something like
select * from myanalyze(select * funct1());
or
select * from myanalyze(select * funct2());
