??? I kinda doubt the J-6(and 5)s would do anything against a Hornet other than being a decoy while it is going to its target. (And I really doubt it's worth it to crash 1 aircraft that size into another one.)
As for EA-6B, I doubt it's because of the airframe. The thing is stable and require not too much in fuel. I don't know how much of its tail can come off before it loses control and crash, but it doesn't seem to me it needs a lot. Plus, you have its weight, which is smaller, meaning less stress on the arrestor wires. So it's like the AK, old but reliable. So maybe it is the maintence problem.
If the Growler is to be made, it seems to me that the original 4 crew needs to be reduced to 2, and the other 2 men needs to be replaced by electronics. The cockpit can't be expanded and I doubt they will put 3/4 people in tandem.
But that's for the other Hornets. As for those fighting China, yes, the Su-27 is the biggest threat now. The J-8Bs, on the other hand, is pretty much nothing. It can't dodge missiles at 4.7Gs, but if the 8Bs are the upgraded ones, then the Hornet might need to dodge a couple of Pl-11s and 12s itself. (Missile dodging ability not confirmed, I'd probably stick more to chaffs out in the sea. Actually, the MiG-29 isn't very manuverable/agile when you just pitched it and it's going stright up, at least according to a sim.) I don't know about what the Su-27s will do against the F-18s. (The Russians said that the Chinese were very inexperienced in BVR warfare during the exercise.) But the number of hits a Hornet can achieve might be very limited.
To popeye: Vacation is wet, as the storms are here, but hey, at least garden is flourishing in the rain.
