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.
