No, that would be a slaughter. Xenomorphs, while dangerous, can still be killed by regular humans with some difficulty.

Doomsday, on the other hand, is known as "the monster that killed Superman" for a reason. And he's only gotten stronger since, due to his Adaptive Resurrection. Hell, according to Death Battle, Doomsday could probably even take on World Breaker Hulk in a fair brawl of strength.
