So we are going to be high ranking officials of the IA/SM/SoB/... who will be more of bickeing bastards trying to get a piece of Gol'kut by sending other people to their deaths?

I have to adit that I liked the previous "dirty dozen" of morally questionable guys more, but I am willing to give it a try since it's WH40k (or 42k?). 

Would it be possible to play something like a disguised space marine from Alpha Legion helping the Consortium or some prominent priest of Mars send to find a piece of archeotech that is supposed to be hidden on the Gol'kut?
