Definitely think that 'precision' based damage types like cutting, piercing and lasers should be much less likely to outright disintegrate a target, while plasma, chem, concussive and incendiary are more so.
A psychic/VooDoo damage typing would also be desirable. I suppose 'Special' kind of encompasses it (or at least stuff that acts primarily on the mind), but it doesn't quite capture stuff like the Ghost Dagger/Beam that affects the body, nor does plasma.
