These sound strangely familiar… xD
They would fit quite nicely. Though we still have no confirmation of the mechanics of Infinity’s simulations, so we don’t for sure know whether it can “layer” something over the body of a Spartan. Though that’s probably how the Flood are simulated, so I see no reason why it wouldn’t be possible. If you can have a Holographic Form Emulator, why not a Sangheili hologram that layers over the body instead? 
And that about a contract would fit in nicely to our (or Didakt’s) Usze 'Taham theory.

Infinity simulations appear to be here for good. I can’t see 343i going against this. It seems to be the way multi-player is heading, I’m afraid.
It doesn’t need to be a part of a simulation, but that just seems to be the way things are headed, unfortunately. But don’t let me put you off though, it’s a nice idea, and could very well be a way for Sangheili inclusion. 
Reach’s multi-player wasn’t canon, and that’s why we had such variety, and little thought for how a certain aspect would fit into canon. This was for the best, was it not? Canon multi-player seems to have more disadvantages that advantages; yes, it is cool, but how many aspects have been taken out due to it? How many more? Is the loss of certain aspects worth having a nice little story? Bah, I guess I’m not really the one who can make a balanced argument. 
Though I don’t think multi-player should have a story-line of its own, 343 does. And so, we need to think of canon reasons for Sangheili inclusion. We can’t simply discard it, unfortunately (again :P).
Went a bit on the rantish side there. Sorry about that. 
Keep coming up with ideas though. The more the better!
