It's a bit rules-lawyery and slightly cheesy, but you can use Time Stop and *ready* a magic missile. I'm unsure if I agree, but there have been those whom I've seen argue that readying an attack is not the same thing as attacking for the purpose of Time Stop's limitations.
The most you could do is spend a daily utility to get a single extra magic missile for that turn, with a specific trigger based on an action.
So, if that specific action is never taken, or your target becomes untargetable, or it becomes inconvenient to target them and you choose not to, then your trigger is expended and you don't get a second shot. As well, your target must be declared in advance.
Lastly, because the triggered readied action is an immediate action, you can only use one of the Time Stop actions successfully.
There's quite a few fiddly bits about using Time Stop to get an extra Magic Missile. It's up to you to decide if an epic level daily power is worth trading away for 22 damage.
