Before starting you'll need to understand the machining capabilities of your team and other available local sources. Do you have CNC or manual
Mills. Skilled machinists on both lathes and mills. Welding or Water Jet? Swerve requires some close machining tolerances to pull off. If you have the some of the capabilities then you can design for what your strengths are. If you have limited capabilities, a purchased solution may be the way to go.

Shifting swerve adds considerable complexity and cost that may not be justified. It's also one more thing that can go wrong. Depending on the game and your strategy it might make sense.
