Only a fool will have ~70 trainers for 7.5-9 million each. You dont put this heavy radar and avionics on LIFTS. Kowsar-I is the most advanced F-5E/F derivative design that has ever existed and by electronics the most advanced aircraft in IRIAF currently. Its better than MIG-29 9.12 ans F-14AM both in that domain. Actually by empty weight it could easily be the most advanced aircraft in its category. It fits right into IRIAF strategy and local infrastructure too.

Kowsar has a T/W ratio of 0.72 with 2 x OWJ Turbojets which give it 10000 lbs and we have a
single crystal turbofan equivalent to FJ-33, called Jahesh-700. Thats what we have in our hands.

Just like FJ-33's larger version FJ-44-4A (20-21 Inches dia, 53 Inches length, dry thurst of 3600 lbf) Jahesh-700 can have larger Version Jahesh-X with 20-21 inches same as J85/OWJ, 50-55 inches length, dry thurst of 3600-3800, Afterburner 7500lbf, which means the aircraft will have 15000 lbf thrust. Thats a T/W of 1.2 with full internal fuel. Such an aircraft with Kowsar's current avionics, FBW, radar etc will become one hell of a fighter. That also solves the F-5E's inherent problem of losing energy at turns.
So same dia, much less length, Jahesh-X version will be almost interchangeable with OWJ J-90. Its reduced length will also make much more room for more advanced avionics in the future or maybe some additional 600 ltr internal fuel for additional range. So with just enlargment we are getting a 4+ gen fighter with AESA radar, HOTAS, datalink etc. Whats so bad about it ?
