My first question to the OP, and not being nosy, how much do you weigh? It is possible that the oem springs are not capable of supporting the chassis properly.
How much do you estimate your service guy weighs?
Adding spring preload via wedges or collars will not increase spring rates. It will move initial net spring ability to support statically. Preload may or may not help depending upon how far off the spring rate is.
In regards to the relocation of the upper shock mounts, this changes the SLR or suspension leverage ratio. In simple terms the suspension does not move in a 1:1 rate where wheel travel is the same rate as shock shaft travel. The change in leverage ratio, which is being dropped towards the 1:1 rate will take a softer spring AND also the shocks damping, and allow them to support more load. Load being static weight, and loads imposed while riding. The tradeoff is a loss in wheel travel.
No doubt Elkas are better than oem. However the the best shocks in the world can not overcome improper spring rates.
The Sway Bar works in a way to couple three items. Left suspension, right suspension and chassis. It effect it does not change the spring rate on the shocks. By design on any vehicle it is to control body roll. It will however in some cases on some vehicles, give similar results when cornering to act in the same manner as firmer springs.
A sway bar on a a bump, parralllel across the road will see the sway bar rotate as both wheels compress. Essentially no force is entered into the sway bar, it merely rotates.
However, if one tire hits a raised bump and the other remains on flat pavement as the Spyder rolls across, the sway bar will see induced twist, which is a slight increase in overall spring rate to the one wheel.
Suspension setup is a book of many parameters. Rider weight, vehicle weight, leverage ratio, riding style, available grip of the tires, rider preference on feel, cost, damping rates, preloads, spring rates, chassis flex, and even sway bars. All this is blended together into the vest compromise from one rider and vehicle.
So without being nosy, I ask about how much you weigh, considering BRP probably chose the "typical" rider at no more than 200 pounds.
All the best with it.
