Kanji flashcards with on-yomi, kun-yomi, AND pinyin?

Hi all,

I've been studying Japanese for years now but I'm preparing to make the push from N3/2 to N1.

My major weakness is not knowing both the on-yomi and kun-yomi readings for each kanji. So, I need to make a dedicated study of all the kanji to improve my literacy.

Since I'm about to drill a zillion pronunciations, I'm curious if anyone has tried studying the pinyin alongside the Japanese readings. For example: [白 = ハク・しろ・bai2].

I'm aware that Chinese has changed radically (pun intended) since 万葉仮名. But if it isn't a total waste of time, I don't mind learning an extra pronunciation for the characters where it makes sense. It looks like there's ~600 kyouiku kanji with the same form in Chinese.

Curious if anyone else has tried this. Thoughts / warnings / resources?
