I haven't done what your asking, but let me ask you this, why do you want to eliminate the rear block?
Is replacing the rear block with a bigger block, to achieve the desired lift, a possibility for you instead?
When I replaced the springs on my Ex, I also swapped out the rear blocks for bigger blocks, which raised the rear of my Excursion.

I still have a little bit of wander. I was thinking that by eliminating the blocks all together and the leverage they exert on the rear axle that could possible be a remedy for my wandering problem. I know that there is a critical angle on the blocks that must be maintained, but could larger springs be shimmed to the correct angle?

When I swapped out my springs, I replaced the OEM blocks with new 3.5" tapered blocks. That gave me approximately 1.5" of lift in the rear.
I'm not familiar with this "critical angle" to which you refer, so I'm sorry, I don't think I'll be much help.
Personally, I don't think the blocks are the culprit when it comes to the Excursion wander problems. I think it's the springs.
I have a post in another thread that touches on this subject. Lemme go find it and cut & paste it to this thread for you.

I found it.
Some people believe the wander is caused by normal deflection of the inadequate front and rear springs, created when the tires travel over the roadway surface, allowing the back end of the Excursion to push-steer the front of the Excursion ever so slightly. This hypothesis also explains why lateral body movement from turning maneuvers, lane changes, strong winds, or towing will induce the wander.
In my limited, lay opinion, this makes sense because it seems some tires can minimize the impact the "rear-end push" applies to the front of the Excursion.
When I had Michelins on the Ex, the wander was not as noticeable as when I replaced them with Toyo Open Country's.
Because of this, I surmised (whether rightly or wrongly) the construction of a tire can dampen the wander effect.
