To be honest, I think you’d be better off just studying words. Studying kanji really doesn’t help you.
If your learning goals are mostly focused around reading, it's helpful a bit.
If you want to actually understand and use the language, hiragana, katakana, vocab and grammar have much higher utility.
My most complete advice would be to focus exclusively on the language you’re learning and don’t futz around with half-measures, but who am I to tell you what to study? If you’ve gotta satisfy the itch, then sure, you might learn something.
