Amazon AWS - Clone IOPS Drive to SSD Drive and reattach

Hi everyone, So -- I started a new production environment and wanted to make sure that I had enough speed, so I chose the provisioned IOPS volume for storage. I installed my application and set up everything that I needed. The only problem was that I calculated the cost incorrectly and the IOPS drive is MUCH more expensive than I realized it was. I'd like to copy the IOPS volume to an SSD volume and then attach the SSD volume to my instance. Let me know if you foresee issues with this, but I presume it should be pretty straightforward using Snapshot.
