First of all, EXCELENT work. I loved everything in this mod. I just would like to add/comment one point:

Maybe the samurai could use a "niten" with katana (main hand) and wakizashi (off-hand) as the duo sword-shield in the standart M&B. In this case, the wakizashi would just deflect melee attacks. Maybe functioning indepently of the main hand weapon. Crazy clicking happening all the time! Or maybe not, but... Well, this is an idea. I really liked the "mortality" of not having a shield to block arrows anymore and not start with a horse so... Well, just an idea...
