If they were to bring them back, I imagine more than anything it would be just to generate a "buzz" around NXT for their USA debut. Part of the appeal of the original Monday Night Wars was the "anything can happen" aspect, where you never knew who might pop up.
In all fairness, they were an okay team who managed to get over. If they hypothetically were brought into NXT they could effectively be used as heels.
That said, I honestly doubt the WWE would bother. While the initial buzz would be nice in the first show, if the rumors of them being as toxic as they were are even half true, it's probably not worth it in the long run.
