Actually, maybe not that much effort, with Item Inspector userscript, or simply with Yomitan (+ Anki Connect).
Even if some effort, you aren’t good to learn that many words per one day. Everything is gonna be gradual anyway.
Only that you can’t have actual Kanji-gated levels, nor simplified SRS system with meaning-reading coupled (though not sure if any of those matters).
Lingual-ninja is a new one. I didn’t see that in Tofugu review website, nor Japanese Language > Resources (and there is this mega thread – The Ultimate Additional Japanese Resources List!)
