We never saw your procedure, but maybe you could wrap it in a function
SQL> create or replace procedure get_members(in_something IN number, out_members OUT sys_refcursor)
is
begin
  open out_members for
    'select level member_id from dual connect by level <= :num' using in_something;
end get_members;
Procedure created.
SQL> create or replace type numbers as table of number;
Type created.
SQL> create or replace function members(in_something IN number)
return numbers
as
  member_cur sys_refcursor;
  members numbers;
begin
  get_members(in_something, member_cur);
  fetch member_cur bulk collect into members;
  close member_cur;
  return members;
end;
Function created.
SQL> select * from  table(members(4));
COLUMN_VALUE
           1
           2
           3
           4
4 rows selected.Variant on same using piplined function
SQL> create or replace function members_piped(in_something IN number)
return numbers pipelined
as
  member_cur sys_refcursor;
  rec number;
begin
  get_members(in_something, member_cur);
  loop
     fetch member_cur into rec;
     exit when member_cur%notfound;
     pipe row(rec);
  end loop;
  close member_cur;
  return;
end;
Function created.
SQL> select * from  table(members_piped(4));
COLUMN_VALUE
           1
           2
           3
           4
4 rows selected.
SQL> drop function members_piped;
Function dropped.
SQL> drop function members;
Function dropped.
SQL> drop type numbers;
Type dropped.
SQL> drop procedure get_members;
