Radious - given that the goal of this mod is different (not historical) I haven't checked what changes he's bringing about.
CoK - I've studies the changes at some point in the past but I haven't found them really changing the gameplay so I haven't tried it.
The problem with the gameplay is that you need both moders with the invention, skills and devotion, and also the testers and players who would tell you how to strike the balance. Just look at DEI, EB, EBII or TATW - huge fan base and plenty of submods. As PikeStance said it doesn't exist for ToB at present. Look at forae at TWC, Steam and TWF - very little substantial discussion.
Besides, I don't see much opportunities in modding the battlefield in ToB. They require very little from the player and there's little potential to change it - both because of the engine but also because of the historical period: this was not the time for the tacticians using terrain etc.
This is, again, very unfortunate since the graphical side of the game is superb and the steering is so smooth and user-friendly.
For now, it's unbalanced and way too easy.
