Well what type of database are you working with, and what type of database if Funcom using ?
What method implementing the backups have they used ?

If you are working with very sensitive data, then it has most likely been implemented with a high flexibility regarding recovery in mind.

You do not know how there database looks or how easy it would be to implement what you are asking.

From the frequent shit storms there are after each update they make, I feel pretty certain that their code base is a dumpster fire.

But if you feel so certain that it would be easy, then ask them if you can’t fix it for them. Because I have 0% faith in their ability to do what your asking in such a short time span.
