Just as you noticed, there are both more Kanji and more vocabularies in the wild; so if you like studying Kanji, you will just have to study more.
If you believe in SRS, I believe vocabulary adding is as simple as Yomichan to Anki, or Kitsun equivalent. Kanji learning strategy is, you might just have to get an Anki deck. There is probably also a Kitsun equivalent.
Nonetheless, I don’t believe in pre-made Kanji decks anymore. Just learn Kanji as you read, and think hard about a learning strategy.
Regarding Kanji, even in WaniKani list, seeing an alternate form, sometime encoded in not only fonts, but also different unicode points (computer binaries), is going to be inevitable too. Just keep that in mind.
It’s possible to export WaniKani, as well as the progress, with the API, to Anki; but I am not sure if someone has made such tools yet. Might be possible to Kitsun as well, but I don’t think you can keep/set the progress there.
