Converting other OSR and D&D stats to 8-12-16 stats

Thinking on how to use the 8-12-16 system for Adventures made in other D&D like systems, I've come up with 2 things which would need converting:

-Any effect which targets a play should be corresponded to one of the Resistance rolls. For example, Saves Vs Poison would be Fortitude, Saves Vs Petrifaction could be Fortitude or Willpower, and swinging blades could be Reflex.

-Any creatures would need their stats converted. To do this simply take their Total Number of Hit Dice. This is now their level for Level Scaling. Their Hit Points will be their Hit Dice times 5. Their Attack damage will be one third their total Hit Points, round up. And their Armor will be their Level/Hit Die plus 3.

I'd love to know if anyone found this useful or would consider running an Adventure in this system.
