Wow that's sagged really bad.
Hooking a gooseneck up is going to increase weight on the front axle actually.
It sounds like those coils are beyond toast to the point I wouldn't use those as a data point for building new springs off of. Sounds like a bad coil or one with tons of miles and are just flat worn out. I don't know about your area but around here people just give the stock coils away. I would try new stockers prior to building your own. Just to make sure you get what you want on the first try.
The stiffness of the coil doesn't dictate it's life cycles
