could we have more types of blood?

there isnt realy enough types, regular blood is ok when you are making a person, but what about aliens, or monsters, or demons? also my knowledge is fairly limited, but can these only have a material thing (flesh with different decals) or can it actually splatter on to other surfaces?

so
it would be nice for

predator blood (green and it glows)
ugony blood (bright blue, glows
sanglehi blood (purple)
android blood 1 (white)
android blood 2 (white/tranclucent)
oil
ash (for shooting demons)
xeno- dark green (alien acid blood)
brown blood
orc blood (black. or incredibly dark)

or is this simply imposible? i also havent seen any playermodels use antlionflesh, so should i have put this in the ideas/suggestions list?
