Getting in late on this one, but if I didn't need to spend money, couldn't spend money, or what ever the reason may be, and the aliasing was something that needed changing on a schedule, then why not just set up multiple alias files, run cron to replace them when needed, and "newaliases", all in cron scripts? You would need to maintain as many versions as required, but sounds like it might work with minimal effort and expense. Complex is a relative term, and this may be oversimplifying, but it would work.
