I think just quickly killing off three of the Brotherhood would seem a bit contrived, even though it's looking unlikely that we will see those three characters again (unless Singer keeps Azazel, who is at least handy as a method of transportation of the Brotherhood - otherwise how do they get around?).
Nicollette Sheridan would be an interesting choice for the older Emma Frost. I think she could pull off the role.
And the Brotherhood doesn't necessarily need a teleporter. They could just show up at any place without showing how they got there. For example, the Brotherhood going to the San Francisco bridge, they didn't need a teleporter to get there.
