well, it could work, the problem is that an image that works for one person might not work for another.
For example, I made these two versions for 客 (guest/customer) :
in one of them i chose a “kiss” instead of winter+mouth because winter+mouth is actually the radical for kiss in wanikani (not sure why they didn’t use it in this case)
So i just made two versions. Which one will help me remember it more? i’m not sure - but this way, if i identify the kanji as: “kiss under roof” i’ll probably remember the first one, and if i (for whatever reason) identify it as “roof over winter over mouth” then i’ll probably recall the second one.
And a person who isn’t me - might not find EITHER of these useful and maybe they’re struggling with the reading instead of the meaning so they’ll want an image that emphasizes きゃく somehow…
