I agree with Mark. I also don't care for your example. I don't have the full context, but it seems to me "wicked" is too strong a modifier for "mocking", which I tend to think of as harmless ribbing. But I grew up in an unforgiving neighborhood, so perhaps I am more callous than most.
If consonance in general appeals to you, I'd suggest it could be a character trait for one of your actors; sometimes funny, sometimes awkward: That's who she is, it could give her a distinct "voice". You can point it out by sometimes having other characters make fun of her for her more strained efforts at consonance.
