Ask-Magical-Total-Drama Redux: Pahkitew Island

I'm using my Deviantart account to write about my Tumblr sideblog. Oh, the wonders of the computer age. 

As some of you may remember, I run "Ask Magical Total Drama," with the TD characters in a Hogwarts AU. I discussed the season 1-4 characters here, and now I'm in the process of trying to integrate the Pahkitew Island cast. I wrote down some thoughts on Tumblr, but I'm still having some trouble with the Sorting, especially since I'm trying to keep the Houses and male/female ratio as balanced as possible.

Here's what I have so far:

Gryffindor
1.) Jasmine: Seems pretty obvious.
2.) Sammy: I considered putting her with Amy in Slytherin, because she does prove to be pretty sneaky, and others have suggested Hufflepuff, but I figure this way it be sort of a "Neville Sorting" and represent her standing up to Amy. Plus it facilitates her friendship with Jasmine.
3.) Sky: The more I think about it, the more I want her in Hufflepuff, because of her emphasis on teamwork and fair play. Even her issues with Dave (and Keith) could be seen as being "too nice" to be as firm as she needed to be (if you think she wasn't, let's not argue that here). But Hufflepuff already has four people...some have also suggested Ravenclaw, and she seems to indicate she gets good grades, but that doesn't seem as significant to her personality. 
4.) Shawn: ...Or Slytherin? This actually wouldn't mess up the numbers, but I can't decide—should I Sort based on the character development he undergoes during the season, or his natural tendency toward self-preservation over others? This would also add a "good Slytherin," which I kind of like on principle. 

Hufflepuff
1.) Rodney: There's not really anywhere else he fits.
2.) Ella: Yeah.
3.) Max: I feel strongly that he is not a Slytherin. Is he crafty? Hell no. Ambitious? Not really; he says he wants to rule the world or whatever, but he pretty much just goes around acting as "ee-vil" as possible. Plus he coos at babies. He's clearly a Hufflepuff who's just putting up a front. Honestly, my second option for him is Ravenclaw, because I think he's smarter than people give him credit for (minus one disconnected wire, his mind control helmet totally worked), despite his total lack of common sense. 
4.) Beardo: I guess? He seems rather nice when he actually talks. I might move him up to Gryffindor if I put Sky in Hufflepuff—he's really shy but he came on the show so I guess that counts as being brave?

Ravenclaw
1.) Dave: Because...he's sarcastic? And I have nowhere else to put him? 
2.) Leonard: Well, he's a nerd stereotype. That probably means "smart," right? 
3.) Scarlett: Another of my problem characters, because yeah, she's a strong Slytherin candidate. But I want to balance the numbers, the other Slytherin characters don't fit anywhere else, and as with Slytherin!Shawn, it's sort of interesting to imagine a villain who's in another House instead. 

Slytherin
1.) Topher: Self-serving, sneaky, and he likes Chris (who, in the AMTD universe, is Head of Slytherin House).
2.) Sugar: Sweet but willing to do anything to win. 
3.) Amy: "Bitch" doesn't automatically equal "Slytherin," but she's manipulative and only out for her own good. (And Sammy's bad, though they usually intersect.) 

Just from writing this all out, I'm now thinking of moving Beardo to Gryffindor and moving Shawn and Sky both out. (This would also help balance the gender ratio...hmm. ) Shawn in particular is bugging me, though, because he could fit either way. 

Some other things I discuss on that Tumblr link above:

—I think these guys are going to be fifth-years, while the other contestants are sixth-years. The same goes for any new characters in future seasons/spin-offs.

—I'm thinking of making some of these characters related to the other cast. Rodney and Scott could be cousins, right? I'm also considering Noah and Dave being an uncle and nephew (remember Noah has eight older siblings), but I'm wondering if that's too much of a stretch. Would creating familial relationships mess with canon too much?

I appreciate any thoughts you guys have (on my rambling fantasy world).
