Might be interested. 
So what have we got here... Looks like we've got three fighter types that are good with guns and in Close Quarter combat. But are all loner loners and don't get along with people, and don't do well against the larger mutants. And then we've got Fixer who has money and knows people. Hmm, guess i'll be a scientist type that knows all about Anomalies and mutants, probably Clear Sky, be abit more independent than those ecologists when it comes to survival. 

Edit: On the topic of Clear Sky, in this zone have they been pretty much wiped out? I assume not if there's no Strelok to go to the Chernobyl NPP, so no reason for Clear Sky to be there during the blowout. But they still might have had reasons to go there anyway.
