I,m cheap

I drive a 96 v6 s-10 for work and average 200 miles a day. Its a beater but purrs like a kitten. Its got 240,000 miles on it. Rear springs sag so bad that when I hit a dip I feel the bump stops hit or shocks bottom out. I have a set of b body springs that I know wont work because the segments arent even front and rear. I,m wondering if I took them apart and added the bottom short peices to my s10 springs if it would cause any problems other than being stiff. Trucks not worth spending a lot of money on.What do you think?
