Thoughts on N vs. N (vs. N) game formats

Copied this over from the Subterfuge subreddit - join us!
Conceptually, I like the idea of heads-up Subterfuge, but I'm thinking that drilling up 200 NP might take way too long, and every match would just end with elimination. Part of the reason I dig this game is that everyone needs to strike a balance between the victory conditions -- it's not just "last player standing," and (diplomacy aside) if you just build a military force, you can be easily countered by someone that builds three mines and turtles before you can get to their queen.
The official forums just had a 2v2 tournament start, and I feel like that's a more interesting way to play a very small game, because you can have players take up different roles in different positions. The rule that I don't like from that tournament is the victory condition for it: "the team with the player that comes in first wins." This means one person can just gift most of their drillers and outposts to their teammate and turtle their queen for as long as they can to generate specialists for them; in fact, that's arguably the most effective strategy.
So, I'd like to propose an idea to balance this format, which extends naturally to 3v3 or 2v2v2 or whatever else.
At the end of the game, each surviving player gets a number of points equal to the inverse of their position. (In a 4-player game, first gets 4, second gets 3, third gets 2, fourth gets 1. In an 8-player game, first gets 8, second gets 7...) The team with the most points wins.
The kicker? If you don't finish the game due to elimination (or resignation), you get 0 points. If points are tied, the team with the single player finishing the highest is the winner.
This leads to a bunch of different strategies -- if, in a 2v2 match, one player is dominating the game, all the other team would need to do is assassinate her teammate and they'll win 5-4. (If their teammate survives to finish fourth, it'd be 5-5 and they'll win based on the "highest player" tiebreaker.)
In a 3v3 match, one player dominating the match still needs to assist their teammates, or else they run the risk of the opponents finishing 2nd/3rd/4th to their 1st/5th/6th and winning 12-9. It might even make sense at that point for one teammate to leave themselves open to elimination to boost their teammates' chances of getting 1st and 2nd (and win 11-9); obviously then it would be a 2v3 game with driller output and specialists to match.
