You can't. A Scaling Group is a group of the same resources for scaling, and a Launch configuration is a single configuration to launch an instance.

What you can do is trigger two policies from the one alarm. Go down that path.

It's the "adjustment" parameter of the scaling policy call, as-put-scaling-policy, see the reference

1 means scale up one per trigger, 2, scale up two, -2, scale down two, etc.
