You'd find out pretty quick though, that the double-wrap is an awkward fit into the shackle end. Not that this will always stop you of course, because it can fit, but it usually brings up the same question.
And in case you're not sure about this too, the stock shackles are installed with the open face to the rear.
Another thing that's cropped up a lot lately is the outer spring wrap contacting the metal of the spring hanger. So far this has not been anything dangerous, but in some cases you can hear the clunk, and also see a wear pattern on the metal.
You can still run them this way, but if you are cleaning up the main eye bolt hole anyway (like a lot of Broncos need) you can lower the hole slightly at the same time (1/8" is all you might need). Easily done with weld-washers if your holes are all buggered like so many are.
