Lucina AND Seteth? Yes please! Also as someone who had played every route (except church which I'm slightly more than halfway through) I can confirm Golden Deer is probably the best, and you probably learn the most from it about the 3H world.
I've got Dorothea, Byleth, and I've got a tentative Lysithea muse for three houses.
For Awakening I've got Maribelle, Sully, Olivia, and Owain if you're interested in playing anything Mother/Daughter or cousins, for just gen fluff... Or sad angst, or wild action, whatever really.
Also I can 100% get behind your no incest clause. I've also got Severa if that's a ship you're into, although I get sort of shy with smut.
