Excellent points.
Bottom line is on many levels Turkey for Russia is that Florida for America right now.
There basicaly three major obstacles for more integration.
First - history. For Russians traditionally Turks are slavers kidnapping women from their southern towns. For Turks Russians are Crusaders, eventually grabbing their land and killing muslims covering it as protection of Christians and other minorities. Needless to say all the facts behind it are left in 18-19th centuries and it is barely actual right now.
Second - Cold Warriors. Anti-Russian thinking was reinforced by NATO, with many anti-communist US-educated in the military but the remains of this faction, which by the way was extremely liberal, was all purged by islamist government in 2000s.
Third - islamism but Russians are very expierenced in negotiating this problem. Not to mention they have many allies in Turkey for that cause, starting from socialists and communists to Kurds and Christians and also secularist conservatives. In short - everyone with at least half a brain is heavily pro-Russian in Turkey right now which is a landslide actually.
