I took MrAbbysal's tip and worked it out a bit more, and I think I am now really satisfied with the list, although it might seem a bit character heavy.

Thoughts:
- Took a GotE to pick up the flaming banner and to keep the LD bubble with my core.
- Added the 2nd WP in to give both Knight units hatred.
- The wizards have a pure support role here.
- Kept most characters pretty clean of Magic Items to not hamper my normal units too much. Just added a few basics.
- CC detachments still there for the flank/charge bonus.
- Knights to occupy both or one flank depending on where I might get an oppening.
- Pistoliers to harass and annoy and to kill some warmachines or small units.
