The hijab (etc) is immodest

[R00tKiT]

1) That is not correct.

lol. You probably need to elaborate more on that

2) There is no suggestive clothing anymore. Any way of dressing that remains "normal" has to be enough. 

The Qur'an explicitly commands women to cover themselves. what are you talking about ?
If you understand Arabic, that's the verse about the hijab :  وَقُلْ لِلْمُؤْمِنَاتِ يَغْضُضْنَ مِنْ أَبْصَارِهِنَّ وَيَحْفَظْنَ فُرُوجَهُنَّ وَلَا يُبْدِينَ زِينَتَهُنَّ إِلَّا مَا ظَهَرَ مِنْهَا وَلْيَضْرِبْنَ بِخُمُرِهِنَّ عَلَى جُيُوبِهِنَّ
Notice the part in bold, it uses the term khimar, which means the full hijab.

3) Well. I mostly focus on the book itself. What you are referring to here is “hadith” that is, the teachings that were supposedly given by the prophet while he was alive. But the prophet had forbidden that any of his non-formal teachings other than the Kuran would be written down. 

He forbade his companions to write his teachings when/after he recites the Qur'an, because the two might be mixed up. This restriction is lifted after his death according to scholarly consensus.

Academically speaking, it is a monumental task to determine which hadith is true

Yeah, that's why we have a science of hadith. Hadith scholars who are much smarter than you and me took care of that.

. I mostly focused on the Kuran itself (like the prophet himself wanted future generations to do) 

How do you know what the prophet wanted if you reject his sayings ? 

What a joke

So my view is less traditional, more rational and more rationally debatable if you like

Your view is simply Quranism, and I assure you it's a dead end. The Qur'an doesn't tell you how to pray, nor specifies the number of prayers, and boom quranism is toppled.
