Godzilla/Attack on Titan crossover idea

I was watching Attack on Titan the other night (great show by the way, I recommend it) and I realized how a Godzilla crossover with Attack on Titan could work. In the episode I watched, one of the main characters, who had just witnessed the Rogue Titan brutally kill another Titan, was asking herself if she just saw a manifestation of humanitys anger at the Titans. Then it hit me. The GMK (Godzilla, Mothra, and King Ghidorah: Giant Monsters All-Out Attack) incarnation of Godzilla was a manifestation of the angry and restless souls lost in the Pacific War. So if there was a crossover, wouldn't it make sense for Godzilla to be a manifestation of the angry and restless souls of all the humans killed and eaten by the Titans over the last 107 years? It could work. Of course, the GMK incarnation would be made 10 meters taller than normal, that way he can have a proper fight with the 60 Colossal Titan. I think my idea could work. Also for other fans of Attack on Titan, I've only finished season 1 which ends with the final fight between the Rogue Titan and the Female Titan (who is kind of hot in a man-eating monster way) so please, no spoilers about what comes next. I know the manga came first and is ahead of the television show, just no spoilers please.

Also, I only found the picture, I didn't draw it.
