Hey David!

When you say you are incorporating eversion it sounds as if you may be collapsing into a pronated foot position, meaning the arch is collapsing. This may be why your ankle is feeling more stiff. When trying to mobilize trying focusing more on pure dorsiflexion.

Check out some of the ankle mobilization techniques here and remember try performing them without letting the ankle collapse.
