I'd like to see another Dafydd ab Hugh (DS9: Fallen Heroes, DS9: Rebels, VOY: Invasion! Final Fury, and more)
Dafydd ab Hugh? He started out strong with Fallen Heroes, had two or three decent if not terribly memorable books, and then perpetrated the Rebels trilogy. With the right editor he might possibly tirn out something readable again, but there are other writers with better track records. IMHO, of course. Anyway, ab Hugh doesn't seem to be an active SF writer these days; he hasn't published anything, Trek or otherwise, since the 1990s, and he seems to be focusing his energies on right-wing political blogging.
