Converting NPCs from AD&D to GURPS

I know I tend to do more work then is really necessary, but for my perpetually in the works Birthright game I am trying to establish a metric for converting NPCs.

I originally thought to simply port over the stats. I.e. 12 strength = 12 strength. But I suspect the upper ends are different. In AD&D a Dex of 18 is remarkable, but in GURPS it is almost stupidly dexterous making the NPC mindblowingly talented at every dex based skill.

So here is what I am thinking. Ability scores 2-14 convert at a one to one ratio, scores 15-16 lose one point in the conversion, and scores of 17-18 lose two points in the conversion.

Charisma scores relative to IQ along with concept will inform whether to add GURPS Charisma (an how much). Wisdom relative to Intelligence along with concept will inform me if I should provide bumps (or reductions) to Per and Will.

HT will be capped at 14 unless there is a good reason to do something else.

What do you think? I could scrap direct conversion all together, and build everyone up from concept, but I don't think that will be necessary. Can I have your thoughts?
