Yes. of course it can be done. Springs can pretty much be reset to any lift you desire. However, using stock length springs, and putting heaps of arch in them, wrecks your shackle angle. Think about it, a spring, out of the vehicle, sitting on the ground, will have a certain distance from centre eye to centre eye. Ignoring sag from your vehicles weight when fitted, this measurement represents the distance from spring hanger to shackle end. Now, if you put more arch in the spring, this distance becomes shorter. As your hanger cant move, then the shackle has to, and will stand up straighter. At the very worst, this can lead to the shackle inverting on suspension droop, basically the shackle comes into straight line with the spring, then goes up and fouls on the chassis. Now lay a straight edge from eye to eye, and measure from this down to the centre bolt. This is your arch distance.
To prevent shackle inversion, if you want heaps of lift from leaf springs, you have to have longer main leaves made up. This keeps the eye to eye distance standard, but increases your arch distance. There should be no additional cost getting lifted springs made up verses standards.
