That sounds like the way to go. In terms of reading books (my normal usage of e-ink readers) you don't need 60hz when flipping a page, but it's a must when trying to use an app menu, or using Google Drive for example. Identifying when to increase the refresh rate may be a challenge but I can see it pretty doable for this kind of "limited" scenarios where you either read or navigate a storage app.
