There is an Anki deck that has the kanji cards in the same order as Wanikani. It’s a few years old now so some kanji are out of order, but it’s still pretty solid.
Will link when I find it.
Edit: This is the one I use. [Version 1.05 | 2016-01-31] Anki deck for kanji writing practice - WaniKani / API And Third-Party Apps - WaniKani Community
It looks like it might be discontinued but there’s another one linked in the same thread that you could try too.
