Yeah, Destiny was a perfect ending (and beginning) of the Borg, and I think bringing them back, even for a one off, would ruin that.
Unless it's to bring an ending to the Mirror Borg...
I mean, it seems clear that Destiny couldn't have played out the same way in the MU as it did in the RU, because so much of it depends on Starfleet vessels - Aventine, Titan Enterprise-E, etc. - from the 24th century...a time where the MU has no Starfleet.
I'm sure there could be, for example, an ISS Columbia NX-02, but the rest of it would have to be very, very different.
