Yeah, I'll admit it is hard to judge.
But, your calculation about 8 Toluns is wrong, though not by much; Aselsan gives Sadak 4T loaded weight as 731 kg which makes two Sadak with 4 Tolun on each puts it just over the stated payload capacity of Anka-3 and stated payload capacity of its IWBs, which was 650 kgs each. Maybe it can use them with 3 Toluns on each, or use Sadak 2T with two bombs.
Also, Aselsan's Sadak brochures include a picture of Anka 3 in both dual and quadruple versions.
