Mhemne Gamma World setting?

So in the interest of exposing my kids to all the nerdy SF goodness from my childhood - I have really wanted to run an GW setting for my kids. But I really don't want to get into another campaign, and ruleset, etc. So the idea is to incorporate it into my existing SF campaign, but outside the boundaries of the existing frontier. <br /><br />All that said, I really like Jedion's timeline for the frontier and don't really want to tweak that, other than having the one missing colony ship wind up forming a colony out past the frontier. But the humans' entrance to the Frontier doesn't leave enough time IMO for the radioactive goodness to warp things to the point necessary for a good GW type setting. Also, the humans wouldn't have enough time to build a population density that later was almost destroyed in a nuclear conflagration, from which would come Pure Strain Humans, etc. <br /><br />So enter the Mhemne. They live outside the frontier and have been enslaved by the Sathar for quite some time. Perhaps there are several Mhemne systems, including a homeworld that got nuked by the Sathar hundreds of years ago. They are humanoid and could create a good stock from which to base the Pure Strain and Humanoid variety of characters. Also, a setting like this would be a great place to have the Vimh originate from. <br /><br />If the Sathar 'wiped the place out' they would probably just leave it alone after bombing them back into the stone age, provided they didn't display any ability to return to space. Perhaps a UPF exploration vessel could discover this place and also evidence of a lost lost Mhemne Empire or such like that? <br /><br />Anyways, I need to check into this idea more, and would appreciate input, especially into the feasibility of using the Mhemne like this.
