Turkey saw its maximum advancement under the ruling system that Ataturk had devised for modern Turkey. Industrial development, technological progress, education boost, better infrastructure projects, more structured and organized defence and a strong industrial base in Eurasia.
Going the Ottoman way would totally reverse this. This is the modern world where rules have changed and no matter what many members say, cannot be played by religion. Religion or language or any other categorization will only be USED in politics to gain attention of people. Other than that, it will never go to a pan-Islam, pan-Christian, pan-Jewish etc form of rule that was there earlier. Such a form of ruling was initially seen in Taliban (before they went rogue). And everyone saw what happened to Afghanistan's already fledgling economy. Businessmen, bureaucrats, scientists etc were all replaced by religious clerics who knew absolutely nothing about governance. With zero education and zero awareness of outside world, Afghanistan just went back 3 centuries.
Therefore, Turkey's best bet to rise as a regional player is to become like France; neutral but still influential power that has a non-religious, economical, industrial, national-oriented system with laws the reflect Turkish way of life yet stay away from the jumble of mixing politics with religion.
Also it would take a long time before Turkey can be independent from US. All of its defence is American or indirectly American. To become independent, it should be able to built own fighters, own tanks, own submarines, own APCs (now started), own small arms, own launch systems, own transport aircraft, own ships, own automobile industry etc. Though they're developing these areas fast, Turkey still has a long way to go before it can tell US "Hey that's not what I think.. I think so and so".
IMO Turkey's best interest to become a world player is to continue following Kemalist system modified with an independent stand in the coming decades.
