Well, I don't know how far you've gotten in the Half-elf Ranger Romance, but I, for one, would definitely appreciate a Hildury romance... or, at least, a full romance between Hildury and Sir Nord. Maybe it's just me, but people complaining about no "generic" romances should probably just play BG2. There are plenty of good elf priestesses there. Me? I want some half-orc lovin'.
Edit: Or a Prachi romance. Again, this is dependent on how far you are on the new NPC, but I'm willing to guess that it would be a lot easier to add a romance to an existing character than make one up from scrat
