Tofurious Help -can I change templates easily?

I currently have Tofurious #1. But would like the rotating banner in #2. Does anyone know if I purchase #2, do I have to RE-CUSTOMIZE everything again? or can i simply drop the rotating banner part in my FTP?

(not to make things more difficult, but i’d actually want the “logo” to be the rotating banner, as i did away with the original header/banner part tofurious had established. you can view my blog here: https://johnnabrynnblog.com
