Re eagle from davao, your plans does not consider the type of refueling options. If the F-16V was eventually chosen, the default refueling option is the flying boom. The CART/ART system's development was never fully qualified and does not exist today as an option.
All F-16 operators uses the flying boom system or just go without airborne refueling entirely. If you choose the Saab Gripen, then probe-and-drogue would be possible.
For the FA-50, it would also be contingent on airborne refueling kit being available for back fitting as well as actually buying them. Knowing the glacial pace of procurement, I don't see this capability appearing on PAF's FA-50 in the next few years.
We will need the next few years to confirm PAF's fleet composition (MRF) as well as plans to back fit the FA-50 / Blackhawks with the capability. Otherwise, it is too premature.
