If you are looking for a shooting model outside the family I would suggest either two death marshals or ryle, the guild pawn.
If you need melee support I know the executioner is popular but I personal don't like him, I will go the two extra points for Peacekeeper every time, he's got more wounds, he's got armour, an extra point of defence, with the ability to burn a card to walk he is really quick, I believe his damage output is a little higher...
basically they both have big targets on em, the difference is the Peacekeeper can take the damage and get into combat fast by essentially charging 13" with two inch reach.
And if all else fails he's got a gun with decent damage, a nice trigger to drag people closer, and it causes slow.
