Swapping springs on a 4.5" RC lift

About 10 years ago I purchased my 2001 TJ off my best friend. He was a second owner who bought it stock from a nurse. All he had done to it when I bought it was a 4.5 in Rough Country lift and 35 inch tires.
I know Rough Country lifts are not high quality but for what he used thr Jeep for he didn't care.

I have since heavily modified the Jeep and use it 85% Offroad 15% on road. In the winter time it is parked.

The back seat is removed and I have a platform built that my dog can lay on, while I keep my 12 volt cooler, recovery equipment, and Chainsaw underneath it on a drawer slide. There is a significant amount of weight in the rear all the time. I have noticed over the last several years at the rear springs have developed a significant amount of sag.
I was thinking about putting airbags back there to help with the weight but I'm not sure that is the correct fix. I think new Springs would be the proper way to fix the spring sag.

I was wondering if it is possible, feasible, and worthwhile to just replace the four Rough Country Springs with new Curry ones and not purchasing anything else? The Jeep honestly handles great, I have no complaints as far as the handability. I have no problem driving at 60 mph when I want to.
I was hoping I could swap out the springs (and replace the shocks) with Currie or Savvy, and not spend money on a whole kit if that makes sense and is possible.

For the record, the whole lift isn't still RC. Swaybars and track bars are JKS. Steering components are Currie.
 
You should be able to swap the 4" RC springs for 4" Currie springs without an issue.

However, if you want to do it right, you'll still cycle the suspension and set the bump stop accordingly. Things could change as far as bump stop and shock travel goes, potentially.
