I think the first thing to be decided is the proportion of voodoo and tech that are used in the resurrection. If it's mostly tech or 50\50 - like the OP suggests, you basically summon a spectre(not the hardest voodoo thing to do) in a cloned body(a mid-tier tech achievement) then why would you summon them in a misshaped body, and summoning someone into a zombie would be quite rude(and gamebreaking, because they have shitload of sense. unless you nerf sense for your people only, then it's game mechanics juggling). The drawbacks would be mostly mental, i suppose the gals who came back to life would be either fearless or scared(depending on a plane of hell they were chillin' at). Think DD afflictions, fearless would be like half armor half resists no CQC, they know there's a life after death and they're cool with that(and maybe don't want to waste time that much plundering this shithole planet), and fearful is the complete opposite, they would constantly panic, get MC'd, you get the gist. Or just chug alcohol in hideout acting like a low upkeed maxed out(i assume you wouldn't res a regular Jane) soldier for crackdown defense. Just some ideas.
And if the resurrection is mostly based on voodoo with barely any tech - like you summon a spectre and then make it manifest a physical form then physical mutations are a possibility, almost an inevitability, along with the mental ones.
