CJ Coil Spring Kits

I've been running a shackle reversal on my CJ-7 for the past few years, but am ready to move on.  I am aware of the BD coil conversion and also the one made by Tomken.  I would like to retain the leafs in the rear but go to coils in the front. Is anyone aware of a manufacturer that is building a kit to do this on CJ's?  I could always go to a custom fabricator, but am a bit nervous about a one-off setup for a Jeep that will never be a rock buggy!
