Don't know if anybody's done this before, but I've been thinking a lot lately about what a Lord of the Rings crossover would look like.
The Hotakainen family would be Hobbits.
Onni is a respectable Hobbit who just wants to stay in his comfortable Hobbit-hole in the Shire and never have any adventures, whereas Tuuri is one of those disreputable Hobbits who somehow ended up with all the Took blood in the family, and wants to run off at every first chance she gets.
...though Lalli strikes me as more of an Elf. Maybe they aren't related by blood in this universe?
I think Emil
wants to be an Elf. I'm not entirely sure if he could pull it off though.
Sigrun's loyalty lies quite firmly with the race of Men. I could easily see her as a shieldmaiden of Rohan.
The more I think about it, the more I think that Mikkel is a dwarf. There are definite parallels with Danish stubbornness, not to mention Moria and Kastrup.
And finally Reynir, I think, is Half-Elven. He hasn't yet decided which race he would rather belong to.
