When we are hypothesising we have to remember there are many factors at play here, a very important one is how does actually Iran see the future of manned fighter jets? I don't think there is any question that unmanned platforms will take a considerable portion of the spotlight in the future. This is not to say they will replace manned systems anytime soon, but what they will do is reduce our quantitative need for manned fighters. I am not going to comment on Iran's UAV development because as we all know that is quite impressive. I feel the future of Iranian aerial combat will be heavily comprised of the integration of manned and unmanned systems. At a recent interview with the airforce commander, he said IRIAF initially were not into unmanned planes but that now things have greatly changed.
When it comes to manned systems, like I mentioned few days ago, initially I can see Iran going for a few dozen 4th gen fighters with TOT and potentially in house manufacturing. In the long run, Iran's solutions must be indigenous. One cannot imagine Iran ever spending vast billion on imports of systems again. Once you have tasted the sweetness of indigenous development in terms of cost saving, pride, less dependance etc, then you will not want to go back. That is why it crucial Iran gets as much TOT as it can, especially when it comes to the crucial technology e.g turbofan so that going forward it can run things by itself in the airforce sector.
Edit: Watch the below interview with the airforce general if you already has not. Here he not only talks about the UAVs matter, but he also hinted at Iran working on stealth fighter designs:
