Relationship History-haplogroup is tempting, but still unreliable . However, apparently the modern Bulgarians are more than 50% of the population before 3500 years .There is no other explanation for the presence of E1b1b1a and J2b2 in all Balkan peoples. Apparently Slavs are predominantly I2a1b. Do not forget that haplogroup accompanying at least 20-30 percent of the above. This leaves little to the proto-Bulgarians / Iranian customs, but turkski language /. .In 681 years have been a mixture R1b1a2 / mostly /, R1a1, J2 and J1 certain and rare haplogroup / G, Q, N, C, /.
Can you tell from where you know the ancient turkic haplogroups? Thanks.
Otherwise I agree with you, and might add some comments:
By autosomal analysis bulgarians and romanians are basically identical. They are basically like Tuscans with less Atlantic_med and more North_euro instead. Look at K12b (my favourite) for instance (1st row - Tuscan, 2nd - Bulgarians, 3rd - Romanians):

The autosomals (coincidentally?) match well the Y-HG. There is no autosomal component where asian proto-bulgarians could hide.
So either Romanians and Bulgarians both descent from Bulgars, or none of them.
There is one small possibility that proto-Bulgarians where purely west-asian (iranians from the caucasus, Balkharia?). They could "hide" inside the Caucasus component, but then again, why do Romanians and Tuscans have exactly the same percentage?
Second, assuming proto-bulgarians were more like Tatars then we should see a distinct asian signal and more north_european. But there is no asian, only increased North_euro, which makes more sense for slavs rather than bulgars. But again the question, why Romanians and Bulgarians have the same North_euro percentage if Bulgars were north_european and ancestors of Bulgarians only?
So far there is no trace of proto-bulgarians, which surprises me also.
