If I just try to steamroller it by ignoring the existing file, I get a ‘405’ error (forbidden method, I think). If I use an FTP client like Transmit, I get a warning about overwriting the file and a manual override.

You can use ‘delete URL’ to delete an FTP file.  If the result is not empty, then it failed to delete it.

You could always try the ‘put’ first, and if you get a 405 error, try the ‘delete’.  If the delete is successful, you can ‘put’ again.  If the delete is unsuccessful, advise the user.
