Can't believe I'm so far behind on these posts. Taking a vacation this week, too, and I'm not sure if that will speed me up or slow me down.
Anyway, I think I was forgetting about prereqs and thinking it could start blackguard after ranger 2/paladin 3, but clearly that's not right.
Anyway, as you suggest, the first 2 levels will be ranger, then I'll choose skills that are in both the paladin and blackguard skill lists just to avoid confusion. Anyway, I will work on that stat block but might try to catch up on other posts first, not sure.
It'd produce better results using the Ranger SPs mostly on Ranger-Only skills.
There's not that much overlap - the two classes only share the skills of Craft, Handle Animal, Heal, Profession and Ride, most of which are of little use for dragon-killing.
