There were few other options.
Either keep her as a guest star, or an onboard girlfriend for Worf. the latter wouldn't have been consistent with Worf's values though, but then even Worf himself admits that some aspects of Klingonness have washed off due to living with humans.
She would have made a good recurring character though. Perhaps she survived getting stabbed by Duras, and Worf gets a kind of revenge by killing Duras in Redemption.
