[Babylon 5] Trouble with Drazi conversions


Has anyone undertaken converting this adventure from Traveller to the D20 version? I know at one point it was in playtest as a d20 adventure but got cancelled a long time ago. Not asking for that, but I am interested in insights from those who may have done this on what level of characters might be appropriate for this, or in porting NPCs to the d20 version. I am leaning towards 1 level per tour, but that might be a bit low. Opinions?
