My answer is NO.
It's just so much cooler to have Kanji, and as a Japanese who studies in China, I probably have the biggest advantage over other foreign students in learning Chinese
I've heard that Korean used to use Chinese characters like us but at some point decided not to. I wonder if for Korean to read their language is similar for Japanese to read an article all written in Hiragana...
Anyways, I can't imagine for Kanji to desappear from Japanese language!!
