My views on Bete have been the same, she pales in comparison to what can be used, now in my eyes Douglas is best in crews with lots of dirt cheap models, Necropunks, Dogs, and things of the like, i find myself killing off dogs with dissection to create flesh constructs and rogue necromancy all day. in conclustion i would do exactly as you planned, punks, dogs, chuahua, and one addition, rotten belles, they are great with the good doc, for drawing people in for doug's, melee.
