You make it sound like someone has to do this by hand.
There are 8 classes (really 4, but 8 sets of companions) There are very few romance options, the quests are the same regardless of gender.
Having played all 8 classes as both male and female, it REALLY is not that complex. The class stories are not as deep as they appear, having leveled multiple alts during 12x class XP revealed. They are filled with a LOT of fluff and travel.
The only reason to do this is a lack of interest or desire, not because it would be overly complex.
