Myanmar's JF-17s Block II were produced in record time (2 years from order). Should there be an order, I am sure 2.5-3 years from now it could be managed.
Regarding costs: will depend on what options you go for. Myanmar paid 16 million Usd per plane.
PAF is projected to have 250-300 units, and another 150 at least will be procured by China. Other customers include Nigeria and Myanmar.
Other than sticker price, a quid pro quo could be arranged with Indonesia not having to pay it all in cash but in other products / commodities / equipment.
To see comparison of JF-17 and F-16 type "JF-17 F-16 comparison turn rate" to see a turn rate comparison with the prototype block I. JF-17 should be able to turn inside an F-16 marginally.
Jf-17 is basically somewhere between an F-16 and an F-18. Will have higher ITR than F-16 but lower than F-18. Will have higher STR than F-18 but lower than F-16 at altitude.
