Or not, but I am just saying that a Revenant can push the boundaries of what is possible, including substantial changes in physiology, either biologically or through surgical or cybernetic alteration. Being crippled pays the price.
Added onto which, we need all templates to act like humans (save those with Alien schticks, which have their differences precisely defined) and we don't want to be worrying about an injuring shot also depressurising a character.

Backstory: The very idea of a Skakoan Jedi, dark or not, is indeed a strange and unusual notion. This curiosity was not lost on the Jedi masters who saught him out as an infant when they felt the Force flowing through him like a powerful current. Taken into the Temple, he was to be raised as one of the Acolytes: powerful, sheltered channelers of the living Force itself. And, for the time he spent there, he learned well how to control his abilities. He showed great promise in his future. When he came of age he was sent out on his first mission alongside his Jedi master on what was supposedly meant to be an easy task. Settling a simple dispute between feuding organizations on a nearby Republic world, neither he nor his master expected hostilities towards them. Hailed as ambassadors, they were instead lead into a trap and attacked by both parties. Vic and his master escaped the conflict, and went into hiding, cut off from their shuttle.
During their hiding, Vic's master saw that his armored pressure suit had taken damage during all the unexpected fighting, and was failing. Vic panicked as he and his master attempted to delay the suit from completely shutting down, with limited results. Within hours, Nic could feel his body wracked with pain as he slowly depressurized, damaging his vital organs and crippling his body fatally. They hurriedly made way to a medical center to try and save Vic's life, but it was too little, too late. Even with the best efforts afforded, the damage was too great, and within just a short time of being received, Vic died undergoing emergancy care. Except, he wasn't. Vic's sheltered life gave him a naive, unknowing view of the galaxy. The idea of death, especially at his age, terrified him. He was told that Jedi who pass on go to be with the Force, but this did little for his temperment now that he was facing a most agonizing death himself. His desire to survive overcame any other thought he had; he abandoned all his discipline to focus on the sheer thought of staying ALIVE. And that was what brought him to the Dark Side.
Vic's willpower, combined with his strength in the Force, brought him back from the brink of death. He forced his lungs to take in air, he forced his body to stay together as it tried to tear apart, through the power of the Force alone, Vic defeated death. Sadly, his miraculous survival was not well received by his Jedi master. He knew that this was only possible through the Dark Side of the Force, and in performing this perverse, unnatural act, Vic had fallen far and hard from the Light in record time. Vic was shocked to see that his master did not recieve him with warm affection for his survival, but with shun and disgust for his unnatural return to life. If the trauma of death was not bad enough, his master's rejection of him flew Vic into a fury, refusing to believe that his survival was an act of evil. He fled from his master before he could strike against him, escaping the medical center and vanishing from sight. With his pressure suit badly damaged, his survival was agonizing, but the Dark Side had fully embraced him now. It kept him alive through what should have been impossible. He was alive again.
Now, it has been over a decade since the darkest day of Vic's life. For him, his old life ended, and he was reborn as something horrible. Yet, he was still alive. Horrible or not, Vic will continue to live as he is, on the fringe of the galaxy, doing what he can to stay alive. He has modified and reinforced his suit, making him more of a cyborg than anything else. His extremeties were horribly crippled from his accident, and so he has learned to use the Force as a means to levitate to get around, opting for handicapped vehicles such as antigravity chairs only when it befits the situation. His arms have been surgically removed and replaced with machinery so that he may keep up with his bodily checkups, and so he may still use his lightsaber in times of need. More than anything else, though, Vic has continued to evolve his grasp of the Force around him, to make himself even stronger to survive. He will not let death come for him a second time.
Essentially, Vic doesn't -need- his suit to survive anymore, as the Force alone keeps him going, but it is much needed for him to do most normal living things, such as speaking properly, and using his cybernetic parts (like his hands).
