40k Dead Space Setting

Okay guys this has been on my mind for while.

 

You see I want to implement not only Isaac, Carver, and Ishi into 40k but also their civilization. Here's how:

 

Their homeplanet, disturbingly similar to Holy Terra is surrounded in a void of nothing but dead planets. So when the IoM decided to investigate that sector they found nothing but dead planets (Numa (homeplanet, still working on the name) is at the center of these dead planets, and is the only 'living' planet). The IoM abandoned their search as it was costing to much resources and believed that this sector was already taken by the Tyranids, but their were no signs of such an invasion.

 

Eventually a daring Rouge Trader sets himself out in the 'Dead Space' sector in order to find his wealth and stake out territory for himself. He finds a lot of the dead planets contain precious metals that would be vital to the IoM continued war effort so he buys the entire sector cheap and begins mining the planets, albeit poorly. Further scouting into the sector reveals an abandoned space station. Curious the RT takes his squad to investigate it. Bring in their first encounter with the necromorphs, everyone almost dies, but is SAVED by a RIG squad.

 

After a very tense stand off between the RIG squad and the RT squad. The two join forces and under the RIG squads guidance, they eliminate the necromorph threat and burn the bodies together. Humanity Fuck Yea!

 

At the end with mental trauma around for the RT squad. The RT guy himselfs in the most polite way what the actual fuck were those things. The RIG squad explains that they are necromorphs and were confused as to why they were so improperly equipped to face them (Once again lasguns are found to be utter shit unless they were hotshots). Que in that both realise that they most likely have been seperated from the IoM for Emperor knows how long (since the Iron Men Rebellion). The RIG squad takes the RT to one of the few safe havens left from the necromorph threat.

 

The RT learns that "Egov" is currently in a civil war (Let's say Isaac and Carver destroyed the Brethren Moons) against a religious cult called Unitology which worship a Xeno artifacts called 'Markers'. After the 'Brethren War' humanity has been slowly losing to the fanatic Unitology soldiers and their necromorph pets who are smuggled into Egov owned planets and space stations and set loose.
