MJ Rear spring on XJ for lift?

I was wondering if you could easily use a Comanche rear springs on a XJ for lift in the rear. I know the Comanche Springs are arched but was unsure about the length and width. The Jeep is a 92 XJ with a 3” add a leaf and I am looking for more flex and about 5 inches of lift.
Thanks,
Marcus

You can shuffle the individual leaves together and make a bastard pack like the well documented Dakota and S-10 mods, but the eye-to-eye length of the MJ main leaf is much longer than the XJ main. That's what gives MJ's so much rear travel.
