[@Kassarock] You most certainly could. All of these characters are meant to be underdogs, underachievers, that sort of lot. You could play a commoner who hardly knows anything of fighting or stealing, or is perhaps just terrible at both. The premise does revolve around a group of thieves, or petty criminals, so you would to figure out some sort of way to be incorporated in with the group. At some point in the near beginnings everyone will be thrust into a group by some means, most likely incarceration for some sort of petty or high crime.. at which point the group will become established and will embark from there.
