Existing Outlook.com address, want to add it as an alias to another account?

I have an interesting issue... I have a primary @live.com email address that I use for basically everything including my MS account. When Outlook.com launched, I rushed to reserve my name, and got it (woo hoo!).

However since that account and my @live.com are separate, there's no way to link the two, and I want to have the @outlook email as an alias under my @live account. How do I go about doing that?

I have thought about closing the latter account and then trying to register it as an alias, but doing this with a test email account didn't work (I created *** Email address is removed for privacy *** and then deleted it, didn't let me register it for my alias).

So what is the process to do this, so I don't lose the reserved name?

Thanks for any help!
