Extra model time? You just said yourself they incubi are basically dreadlords, so why not take the dreadlord, scale the model down to that of the Succubus and be done with it? Thats like a 30 minute job for a coder.
Because that would be silly, dreadlords are evil scheming bastards, and wouldn't suit the role at all. Chris Metzen may be good at retconning things, but dreadlords are to far away from succubi even for him to retcon.
