Yeah !! Plus with Ville's really positive / optimistic / happy-go-lucky attitude that really made me think of Reynir and Tuuri, like probably how a child raised by those two would behave.
And then there's Hannu . . not only does he look like Lalli with the cheek bones and his light blonde almost silvery hair, but it's mostly his personality that makes me feel like he's a good blend of Emil and Lalli. He's someone who strongly prefers his solitude and alone time like Lalli, but he's also pretty spoiled (as described in his bio) just like a certain Swede and as a result can be pretty, well, Hannu. I know I saw more personality similarities but it's been a while since I've read aRTD so I'd probs have to re-read it before writing anything.
Ville is exactly like a doggy Reynir! He's definitely the kind of person who grew up surrounded by love, and I'm sure any child of Tuuri and Reynir's would have nothing but a loving childhood. Maybe a bit of a magical childhood. Reynir's a mage, most of Tuuri's family are mages, so any kid of theirs would probably be magical enough to, I don't know, turn off their personal gravity and float around.
And Hannu as Emil and Lalli's child kind of works too. Emil's immediate instinct would be to spoil the child. But then I also kind of think Lalli would be a no-nonsense dad. If I were ever to consider a situation where Hannu was the kid and Lalli was the dad (though my head canon is vice versa, and pretty firmly established), I think they might butt heads. Lalli telling the kid not to be so stubborn because it's gonna make his life difficult. Hannu telling Lalli to stop trying to run his life. Emil stuck in between them like 'guys be nice'. I don't know, I feel like they'd love each other, but they'd clash a little bit for being so similar.
