The Hürjet will definitely need more powerful engines for its transformation into a multi-role fighter jet. There is one official information we know, and that is that a preliminary study is being conducted for the Naval fighter jet version of the Hürjet. I think there is an evaluation of a lighter attack jet that will have a cheaper production cost than the MMU. And this jet will probably be a jet similar to the Gripen concept, which can operate from short and raw runways, and this jet will also be structurally navalized.
There are two possibilities, one of which is to move towards a single-engine MMU design after the current configuration of the MMU becomes operational. The other is to change the engine design of the current Hurjet and expand its wing area to become a 4.5++ fighter jet with a 30,000 lb engine. The first would be a stealth design philosophy while latter an operationally cost-effective approach. The second way could enable the Hurjet project team to stay on their track for a longer future.
In any case, I personally don't think the force would prefer a jet with 17,000 lb thrust and 2700 kg ammunition capacity, as combatant platform. Anyway, unmanned jets with this lift capacity and even mission profile (altitude/speed) will be offered to the service of the force within a foreseeable range.
