I'd suggest that another set of Wicked Dolls is a bit of overkill. You can quiet easily pump out half a dozen of the little boogers with Mrs Z and the WW, but it won't happen all the time, and if you're just playing for fun then you could proxie something else if you need more than 3 on the board and save a bit of cash.
As an alternative use of your money, what about the Brutal Effigy? He'll give you some range in that doll list, will help keep WW and Teddy alive with his healing, and also goes great with the Dark Debts crew for the same reason.
