I like this idea. But why make them humans?
Like Nash said, Nepleslia is already the bastion of humanity. Aren't Nepleslian regulars supposed to be entirely human? Sure, a lot of them get cyborg implants and many of them are clones, and surely the majority has a lot of genes from genetically enhanced soldiers of the past, but for all intents and purposes they are humans as human can be in this day and age.
We also have too many humanoids in the setting. Yamataians, Geshrins, Nekovalkyrja, Elysians, Nepleslians, ID-SOLs, Freespacers, Jiyuuians (if those still count), Iromakuanhe, Abwehrans, Loraths and up to a certain extent the Azoreans and the Kohanians are all humanoids. They are all also the only Role Played races, just about (except for the Misshuvurthyar, but those are Role Played exclusively to have enemies in the setting).
I think we should start promoting other races that aren't humanoids. The lack of variety is making the setting get stale, in my opinion. There should be other alien races that get role played that have no human predecessors (as most of these pseudohumans do) and are not humanoid at all.
I vote there be another race that fits this role. It could be any race. Personally, I would like to use my
Checztians for the task; though they might require some tweaking to fit the task at hand (particularly when it comes to their history). If not, then at least any other non-humanoid race.
The setting is looking too much like Star Trek, really...
