Yes, the ROTJ yoke is the same design as the SW yoke.
Here's the SW pinout if you want to verify.
Star Wars harness pinout (Thanks to Ninten-doh for the original image and to Gray_Area for clarifying the wording)
The only
very minor downside to the USB adapter that wp34 mentioned is that you'll need a separate encoder for admin buttons like Coin, Pause, or Exit.
You can handle both the yoke and admin buttons (or just the admin buttons) by "rolling your own" encoder using an Arduino Pro Micro or similar AVR.
