[EDIT] Alex beat me to the punch a little.
You can contact AN via their contact page and ask if he (Toru) has something similar or can he get it!
Below there are artisan examples from another vendor. You can then click on one image, and it will open another page ... then click on the artisan name if it is blue
.. . which will take you to the artisan's page which will have other offerings from the same artisan that may not be pictured elsewhere!http://www.tokoname.or.jp/teapot/gallery.htm
Below is their general and incomplete catalogue. You can email then and ask if they can get you something of a similar style. I would not disclose the price your vendor is charging however ... http://www.tokoname.or.jp/teapot/yubi13-ru/yubi13.htm
I have never used this vendor, but have looked numerous times. Other members have been satisfied. BUT be sure you clarify in communications that you are getting exactly what you think you are getting ... such as size, filter type, etc.
