If they are looking for new aliens to appear in the second season of 'Enterprise', which I'm sure they are, we don't want to see any more of those aliens that never appear again in Trek, or that we see, but we never find out who they are. So, here's an idea: why not introduce the Kzin?
The Kzin appeared in the Animated Series episode 'The Slaver Weapon'.
Felinoid aliens have been a staple of science fiction, yet up to now none have appeared in Star Trek, probably due to the expense of creating the make-up and special effects. The Animated Series had no problem with that and thus the Kzin made an appearance.
There is a webpage here, that attempts to reconcile the appearance of the Kzin in 'The Animated Series' with modern Trek:

"Sulu mentions in "The Slaver Weapon" that four Kzin wars were fought between the Kzin and humanity two hundred years before the episode. Placing the Animated Series after the third season of The Original Series and before Star Trek: The Motion Picture, that would fix the date of "The Slaver Weapon" to approximately 2269 or 2270, setting the Man-Kzin Wars no later than 2070. Even allowing for inexactness in Sulu’s line, these wars would not have lasted into the 22nd century. Early Star Trek fandom would date these from 2049 through 2064, but there is no evidence of any face-to-face contact (more likely space-to-space combat, much like with the Romulans in the Romulan Wars: neither side having seen the other face to face until much later)."
So that would place the Kzin Wars smack in the middle of the 'Enterprise' Era.
You really shouldn't mix elements from one sci-fi universe into another universe unless you have a very good reason to do so. There is no way to mix the whole 'Known Space' and 'Star Trek' universes together. But, given that the Kzin have already appeared, and it was the author Larry Niven himself that did it, do you think we should see them again?
