What 118 currently does as far as I know is use all 17t sprockets and use smaller diameter wheels on the corner, causing their larger diameter wheels to have greater linear speeds than the outer wheels. Jack's idea is a possibility to fix that problem without having to implement a drop center.
Is that a problem? Teams have been running uneven diameters for a long time.

Your wheels are slipping in one way or another in any motion other than going straight anyway.

The normal force is highest on the inner (larger diam) wheels as well.
