NPCs on Mounts?

[merb]

I was just wondering if it'd be possible to get an NPC to be on a mount. I know they'd have to be a PC model for it to work. I've tried making them do the #npccast command for one of the horses and if it works at all, I make sure they are added to the DB and I zone out and back in, but no more horse.

I thought a solution could be to add a quest file to the NPC which puts them on a timer to cast the horse upon spawning, but I was wondering if there was any other way or if the quest would even work.
