Yes princessletcia. However, it still does not rise above slang expressions, and it is only acceptable in casual dialgogue, and it would not be acceptable in written contexts. One doesn't want to use slang like this on job resumes or any sort of autobiographical account. Rather than claim to BE BIG, it would be more appropriate to indicate that you favor history over all other subjects, or give expression to the idea that History takes precedence over all other subjects as your greatest area of interest.---Warm Regards, Bruce

The phrase "I'm big on X" means "X is important to me". It's quite different to simple enjoyment. To answer your question, yes you can use that pattern. Here are a few examples harvested from online: "I'm bigger on layout and moving features around to optimize user flows than on the actual look." "I'm bigger on the politics than on the philosophy." "I'm all for guns and ammo deals, but I'm bigger on safety!" "I'm bigger on resonance with the hero, than the villain's own tragedy anyway." In all cases, "bigger" signifies a greater importance to the speaker.
