With the work done on the gore in this game, I would be a lot more pleased if the cyborgs had their own special type of gore (besides bleeding oil), like maybe a cybernetic exoskeleton when their cyborg armor/skin comes off (ie: D'Vorah's first fatality), and when they are shot, like in Cassie Cage's first fatality, sparks fly off when it impacts through the armor. Maybe even when limbs are severed, there's buzzing and sparks of electricity from where the body parts separated.

For Reptile, though, I wouldn't mind if they copypasted the red human organs and made it green, because he's basically part human (but still part lizard).
