Until you know exactly how far you need to move them it's going to be tough to get a definite answer. The main problem I see is that any relocator is going to screw up the C/C width on the spring center bolts, so you are looking at moving the perches on the housing in any case.
The last 1st gen we did had 10 1/2" of tire clearance (12 1/2" total) from the spring to the fender lip, IIRC.
Your tire is roughly 13 1/4 ", so you would need to get to 15 1/4" minimum from the fender lip to the spring. That's 2 3/4" IF I'm remembering it correctly...
Don't see that happening without moving the axle perches and re-designing the front mounts as well.
