Players Who Own FFXIV Version 1.0
Players who own FFXIV version 1.0 will not need to purchase the PC version of FFXIV: ARR and will be able to download the FFXIV: ARR software for free.
* Details on downloading the FFXIV: ARR software will be provided at a later date.

Furthermore, users who have version 1.0 registration codes that have not yet been registered will be able to register them and play FFXIV: ARR on PC at the start of the service.

Based on that it seems possible, might be worth a try. Just remember you will only get 2 weeks of play time and not a full month.
