If you need to cut out weight, the planing method will likely leave you with the strongest and stiffest structure. If you have access to a large milling machine and a fly cutter, it's just a matter of manual labor.
The 3" spacing on the bearings is a big factor in how strong your rails have to be. A wider spacing means that the elevator rails see less stress and don't need to be so bulky, which can save a lot of weight with the tall single-stage elevator approach.
