I would rather recommend your solution of writing a custom .NET component which will fetch the file from FTP location (you can call that component from your expression shape).

I'm not sure if this link helps - specifically the CreateFtpReceiveLocation method - i.e. programatically adding a receive location (pseudo dynamic receive location).

You would also need to remove the location afterwards. I'm guessing that you can also set the FileMask on the Transport Properties of the 'dynamic' Location to the filename in the Custom Props of the TransportTypeData, and would need to remove the Location once you are done with the file.
