I wouldn't necessarily go with romaji (and apparently no one else either), but dumping kanji would certainly simplify things a heck of a lot!
If Japan went with a just a kana based system it would be so, so much easier to learn. Switching to single blocks for the compound syllables could even retain a lot of compactness.
The added complexity is glaring when you compare it to learning Korean.
@nikunashi Idk, strings of pure hiragana are pretty hard to parse, at least in reading. Some kind of delimiter would come in really handy, if Japanese is to become a kana-only language.
