I think even two TEI TF 6000 engines won't be enough for such a load. There were rumors before that it would have two engines, but I don't remember which ones.
What about a single TF 35000 engine? Would that be suitable? Even if not, I think it would require minor modifications. And as a fighter, it would be superior to the current version with a Ukrainian engine.
Too expensive, don't forget these are disposable products where the loss is factored in. Even if it only carries payloads of 4-5 tonnes, that's enough. It's supposed to take over some of the missions, not all of them. A total of 12,000 lbf with 2 engines is enough to carry these payloads; the drone moves in subsonic space anyway, so more lbf is not necessary.
Don't forget Akinci has 2x Turboprop Engines, and the drone carries a payload of 1.5 to 2 tonnes.
In addition, an A-10 has two 9000-lbf engines and can carry 7-8 tonnes of payload, and we are talking about a CAS and air-to-ground aircraft that has to carry even more complex electronics and equipment for the pilot. None of that applies to drones, so 4-6 tonnes is very realistic, as they fly at subsonic speeds of 800-900 km/h.
