Clerics and Druids dont seem like a big Problem, i'm not finished with the npc chapter, but there seems to be only one cleric and one Holy Warrior as major NPCs, both could easily be based on Faiths that exist on Yrth. For the Location i would say Caithness is a perfect fit, just use the Border to the Great Desert in the West and the only thing you have to change is rotating the directions 90° counterclockwise.

PS: I think Transhuman Space and Traveller both outperform Banestorm when it comes to details
