That’s cool, but be aware that any problems and bad mental habits it teaches most likely wouldn’t be evident until later when you’re focusing on learning vocab and don’t want keywords getting in the way.
Also if you’re doing it both ways then naturally it will seem like you’re remembering better because you’re effectively reviewing a character twice as often as Anki wants you to. The question will be whether the space is still long enough for the SRS to work effectively and move the information into long term memory.
