I think you have to put yourself in your boss's position here. They may be aware of tensions around this person. They may have already decided that you would not be able to handle it as well as others. They may have decided the opposite, that you, above anyone, would survive the situation.
But, whatever their thoughts, you are putting them on the spot by raising the issue. You are essentially telling them how to do your job. You are also telling your boss that you're willing to throw your teammates under a bus to get your own way. No matter how you see it, that's how your boss will see it.
If your boss is unaware of any tension, you might get away with putting a positive spin on this, as others have suggested. But you are going to need to get a colleague onside and to do so (particularly if you try to work on two of them) might create a Prisoner's Dilemma for them.
And, if your boss is aware, and is undecided as to who they're putting in the room with this person, they will see through any positive spin you put on it and will know that you're working in your own interests, against your teammates'. You may be flagging yourself as the most expendable person on the team by showing yourself to be untrustworthy.
Personally, I would wait and see. This might not be an issue that needs dealing with. And, if it does, then I would suggest waiting until there is a problem and then raising it directly, with evidence.
