Sorry to disagree with a colleague, but no.
Think about this: a veeam proxy, in order to work in DirectSAN/Storage Snapshot mode, needs to be connected to the storage fabric in the same way as an ESXi server is. So, with FC, also the proxy needs to have an FC connection. I don't see how a virtual machine can have an FC connection, and if the answer is "NPIV", well I'd stay far away from that solution, is not something you want to do. Go physical.
