I've been doing a lot of this Pathfinderizing-comic characters sort of deconstructionist/reconstructionist character building lately, so I find this installment of the Workbook particularly interesting. Those sequences you used to help establish Red Sonja's character type almost seem tailor made to set her up as a Ranger- if I didn't know better, I'd say that Ms. Simone was a roleplayer herself (I assume these are all from her run?).
(She may actually be; I should know but I can't recall.)
In any event, though I'm not exactly well-versed on Red Sonja's character and appearances, based on my own comic reading proclivities, I'd say you could do far worse than use Gail Simone as a primary source. From what I understand her RS run was particularly good.
(And I'd highly recommend her first run on Secret Six to anyone that hasn't read it. It sort of begins to run dry by the end of that series, but I suspect that had more to do with increasing editorial demands with crossovers and DC leading into their New-52 reboot). Come to think of it, it would be fun to stat up the Secret Six Pathfinder style.
Maybe when I get finished with the classic Thunderbolts for a twist on a Hell's Rebels campaign.
