Thanks! Despite enjoying the sun today with some cycling and tennis, I managed to get a few more cultist over the line. The addition of Heironymus Krupp, the magister, Heinrich Spol, a mutant, and another anonymous darksoul brings the Cult to well over the 500gc starting level for Mordheim.

The opening line up will be the magister with two daggers, the Possessed with scorpion tail, the mutant with great claw and club, and a brace of beastmen with heavy armour and two-handed weapons.

I'm now planning to add various other Possessed and mutant options, along with more varied henchmen (brethren and 'lighter' beastmen). It occurs to me that it would be worth converting the mace-wielding darksoul to give him a flail and match the other; I might do that if the bits box yields a suitable length of chain.
I'm now trying to find a similar hack/cheat for Skaven - got a few ideas ...
