when i was Col of 18th we were having ideas with 2v2 Linebattles..... its literally as basic as it sounds, 2 regiments vs another 2.... each team has many ways they can go about it, e.g. stick together, pretend to be 1 massive line, or 1 line distract while the other flank.... any similar concept to those would interest me. either way gl with whichever u choose kinky!
Edit: so NWBC pretty much is what im saying, but with however many regiments u choose per side.
