when we transfer your Kongregate Account to an id.net account it gives you a large warning message that this cannot be reversed. The reason why is because the transfer involves taking the old Kongregate data and using it to overwrite some of the id.net data in the database.
I'm sorry to say the warning is accurate, this process cannot be reversed in the current database - whatever experience and items you had in the id.net account has been replaced with the Kongregate data that you transferred over it.
That said, I will send you a Private Message with some questions, if you can answer them quickly and work with me on this, there might be a way to get something back out of a database backup - although it probably won't be 100%
For other players about to try this, the best idea is to create a brand new id.net Freefall Tournament account (there is no limit on how many you can make) and transfer to the new one. Then if you decide that the progress on your original id.net account is better, you can just switch back to playing that one.
With my access to the live database almost anything is possible except for recovering data which has been replaced by other data.
