I think there's already been a thread that asked this, but not a poll.
The choice of adoptables is heavily biased towards Nords, as you'd expect in their own province, but how would you choose if you had more options?
I'm asking because I'm making an Elf Kids mod, and want to know others' opinions on the Skyrim adoptions. I'm not yet planning Khajiit or Argonian kids, as they'd need a lot more model work than the elves, but it could happen in the long run, after Orcs.
The WIP mod so far replaces Sophie and Alesan with Dark Elves, as each of those was added by Hearthfire, and makes more sense being Dunmer. The High Elf children are in the basement of the abandoned Thalmor Headquarters, and the Bosmers aren't done yet - location ideas wanted! I'd also like an opinion on whether the Bosmer kids should be shorter than the others. I didn't (yet?) make the Altmer kids taller; I'm assuming they just grow for a longer time. Skyrim's kids all being ten years old makes as much sense as Oblivion not having any.
My own starting vote was for Fleur's kids - she adopted Sofie the flower girl, and Lucia from Whiterun, since there are no Orc children, adoptable or otherwise - and I realised after voting that they're not the same race, being a Nord and an Imperial.
