Honestly I am not a fan. There is a reason the number 12 is so prominent in military organization throughout both history and fiction, and that reason is tactical flexibility. The number 12 can be broken into sub units of equal size by singles, 2, 3, 4, or 6 thus giving you the options of splitting the force to suit needs. IMHO the Inner Sphere/Star League deployment methodology at that level offers, for its size, an unprecedented level of flexility, and that is if breaking to equal sub units. The capability to Harry with 2 or 3 independent small units and the solidification of half of the company for a stand and city is always an option too. I don't like the rigid lance structure, but it does fit giving each "by two" a wingman so to speak, whih is not bad thinking at all.
