Could I get away with using the Astro-Physics 4" Prime Focus Field Flattener, originally designed for the AP 155 f/7 refractor, on a TEC 160 f/7 refractor?

It would probably work optically, but the mechanical design is quite different. The TEC FF attaches directly to the threaded end of the focuser draw tube. It looks like the A-P part has a dovetail and would need a special adapter.
