you know, I’ve actually found it much much easier to take a look at the radicals once, cheat everything until you unlock the vocab and then learn the associated kanji at the same time. learning a bunch of words at the same time as the kanji and mostly ignoring the radicals altogether has worked much better for me…
I think vocab is much easier to remember because it tends to have more concrete meanings. And once you’ve learnt a couple of words that contain a kanji, linking them together and learning the kanji is really easy.
wore one to a wedding last week 
and it took me many many attempts to tie it properly because it’s been so long since the last time 
have you tested this in the real world? because ime it doesn’t work like that in most cases. in practice if you know the kanji it might make looking up the vocab a bit easier assuming you actually recognise the kanji turns out recognising kanji in an actual sentence is yet another thing you need to practice
as far as script recomendations, I think this is the best script for learning the readings of kanji quickly. it should really make it into base WK
