Why not eliminate the gang combat bonus (restoring the points spent of course), and add gang stat bonuses for all the stats? Basically separate it completely into it's individual components.

Perhaps make them temporary however, so they are affordable and people don't feel they are screwed if they get something they don't want. Say for 1 point added to a stat it's 10 gp per player per day or something of that matter. And make the cost escalate the more you add to 1 stat. So say you want a gang resistance bonus of 3 for 3 gang members. Have it costs 180 gp for the day.
