[KrazyCarl92]

These papers discuss this topic well:

mecanum X & O square & rectangle
mecanum force vector analysis

Note that when most people talk about X & O orientation they tend to talk about a bird's eye view, whereas Ether in these papers refers to a worm's eye view. An X viewed from the top is the same setup as an O viewed from the bottom, and vice versa.

Pretty sure my team was at this point at one time...

No amount of code will "fix" the issue. The mechanics of an O-oriented mecanum drive as viewed from the top will result in less optimal turning than an X-oriented mecanum drive. This is explained in the papers.
