So the pots look to be board mounted which means it will be a pain in the ass to rehouse because of creating a new enclosure layout. It's doable, but you'll have some work on it.
Agreed with not heating the iron up until you figure out if you can even get it in a box. Now, you ought to be able to. I know some tricks here. Since the Proteus is so small and the holes are the same on both side, you can just flip it on top of the new box and trace the holes. Does that make sense? You know what. The Prometheus looks to be the same way. So the biggest pain in the ass it adding extra wire or de-soldering shit so it will fit right. It's definitely doable though.
