2" probably isn't a good place to move the pin. That puts the old hole right at the edge of the axle pad. The old hole will be a weak point, and having it right where the axle pad will stress it as the axle twists could cause the leaf to break. Depending on where a main leaf breaks, it could be VERY bad if it happens while you're driving.
Do you have a drill that will cut spring steel? I guarantee that unless you have commercial grade bits, you'll just dull them trying to drill a spring leaf. A leaf spring is harder steel than a hardware store bit. My buddy bought some commercial bits, cost him nearly $250 for a set of 10.
www.alcanspring.com can make a new main leaf to your specs, then you could just bolt the rest of your leaves into that. Might be cheaper in the long run. They could make you complete new packs but they are pricey. I run Alcan springs on my Jeep and love them.
