Can't you just include the "out" parameters in the result?

CREATE or replace FUNCTION public.test(x integer, y character varying(36))
RETURNS TABLE (id integer, filesize character varying(36), x integer, y varchar)
AS $$
begin
x := 42;
y := 'foo';

RETURN QUERY
SELECT t.*, x, y
FROM public.tbl_employees t;
END;

It's different because x and y are repeated for every row, but that's the only thing I can think of.
