[Prototype and Mass Effect] If Alex Mercer were to survive to the 22nd century..

Would it be possible for him to consume aliens? He consumed a crow but could he consume a Krogan?

Definitely. The hunters are creatures built by redlight, but they are not mutated dogs or gorillas. Likewise, we know krogan have dna (although its got triple helix, iirc) because of the Genophage, so it isn't a hard stretch to assume that he could learn to use krogan dna. It's Turian and Quarian that would give him pause, because the are dextrose based and their biology is fundamentally incompatible to humans. Quarian are extra unusual, because their biology is made to accept viruses ( they evolved in the world that did not have insects). So how they react to blacklight is debatable. The vorcha, though, are probably the only blacklight proof race, because they have a one time use mega-adaption, and could end up like the two spined hunter. 

On that note,  krogan would require extra violence to consume because they're so tough.
