Qur'an wasn't "changed" so to speak during Uthman's times. It would be impossible to do. It was standardized into one universal reading.
Qur'an of today is exactly same what Muhammad (SAW) dictated. Whether you believe he received it from God or dictated it from his own mind--its upto you and your belief system.
Having said it, it is
undisputed belief in Islam that Qur'an is perfect word of God and unchangeable. Hence, any "change" or any "effort" to introduce "change" in Qur'an is futile. It has never worked in history before, and it never will. Islam isn't Christianity and Qur'an is Bible and Muslims aren't Christian. Islam is vastly more powerful force compared to Christianity and it plays a much bigger role globally in people's life than Christianity does (mainly because of different constructions of both faiths). So lets not waste our time in expecting this "change in Qur'an" to come. It would not come. You know it, I know it.
However, you can always come up with better/different understanding and interpretations of Qur'anic text
And this is what should be focused. So I agree with you in that regard. However, Jihad isn't something problematic. You just need to teach Muslims how Jihad doesn't mean insurgencies. You get the drift..
Moreover, Turkish authorities didn't "reform" Hadiths as in they changed or cut-down from hadiths. They just picked hundreds of hadiths out of thousands of hadiths and compiled them in terms of relevance today (Hadiths dealing with education, finances, and stuff..and hadiths about horses, camels, tribal societies are in background (since they aren't much relevant now).
So a "reform" like Christianity (where, with due respect, entire religion was made a joke and was changed by humans..and hence nobody---not even christians--take it seriously no more) won't happen in Islam. And shouldn't.
