Hello all. I myself aren't a fan of Kajiiits of Wood Elves, but I know a lot of people are, and said people are complaining that there are 62 marriable NPCs, about 35% of said people are Nords, but no Kajiits or Wood Elves. I'm sure the other NPCs aren't marriable because they already are. First off, try killing their spouses, see if that works.
Back to my main point, I'm wondering if you can use a console to clone your own character than marry him/her? That will allow you to pretty much make your wife as sixy or your husband as strong as you want. It's just a theory, I haven't tested it out yet.
