The problem with the Hawg is that it's single mission is tied to the Key West Agreement. I'm active AF and control CAS for a living since I left (by choice) the flying side of the AF.
Trust me, anything that ties the AF to Army needs is pretty much bottom of the barrel unless SOF is involved. In fact, based on my operational experience, if it wasn't for SOF missions that called for some of the Hawg's particular strengths, the Hawg would have been gone a while back. Why? SOF helps defray the cost for the capability.
However, just about any airframe in today's inventory that has hard points or a gun can perform the Hawg's mission. Just look at the Marine inventory. Except for two or three vertical lift platforms, everything, including KC-130s, can (and do) perform the CAS mission today. Most of them with do it just as effective as the Hawg does.
In the field, the only advantage the Hawg gives me is that it's the easiest fixed wing platform for me to assess nose geometry while inbound to the target.
Sucks, but it's true.
As for JSF, is it perfect? No. Except for the Super Hornets, there hasn't really been a new strike/CAS platform in the inventory that I can recall in my 17 years. There has to be a replacement sometime and with today's threats, it's going to have to be more JSFish than Hawgish.
