Economy fares are usually sold on the basis that they are not transferable.

Eh? I think you mis-used both words "economy" and "transferable".

Most international tickets sold here allow you to change flight dates
and times, but on cheaper tickets it can be difficult to rebook at busy
times. More so with frequent-flyer free tickets. I have asked to get on
standby a few times, and was not refused, but it doesn't seem to be
official policy.

There is no guarentee, but try it.
