Note that this description isn't sufficient for describing a holonomic drivetrain based on omni wheels. For example, the attached design is not holonomic (source image).

It's neither sufficient nor necessary.

a couple of files from previous CD posts (credits are in the files) that I think you will find useful in your trade-off analysis.

Wikipedia seems to disagree.

There's no disagreement. With the design I posted, you'd be able to control only 2 of 3 DOFs.

I see. The attached differs from the source.

A pragmatic suggestion: seriously consider how reasonable it would be for your team to successfully execute a holonomic drivetrain, for what sounds like the first time ever, starting half-way through Week 3 of build. Your drivetrain is the single most important sub-system on your robot, thus I strongly encourage you to use a low-risk approach.
