I’ve tried doing that a few times as well but for some reason, WK motivates me to be a bit more consistent than Anki (it is a very successful example of gamification… ). But if that is not an issue, that seems like a good route to take.
In case you need a starting point, I had merged this deck: [Version 1.05 | 2016-01-31] Anki deck for kanji writing practice and I think this one: https://ankiweb.net/shared/info/1998142692 and I liked the result
Or maybe I am only using the ankiweb one and generated my own stroke order diagrams… something like that, it was a bit of a back and forth.
I hope things work out well, it sounds to me like you are on a good path.
