Have you considered that different things are difficult for different people? Learning hiragana and katakana has taken me about a month, and I found it very difficult. There is no need to make it prerequisite for starting to learn grammar, forming sentences, or pronunciation.
If you want to learn pronunciation you should be listening to audio.
Sure, maybe don’t force people to learn kana first. But Hepburn is kind of the worst of all worlds, it is just a waste of time to learn Hepburn.
Notice how I didn't say that I "learned" both in a day, I "remembered" them. Of course actual learning will take some time, especially with less used characters. But remembering shapes and differentiating between them using mnemonics should not be too hard for most people.
