Merging 2 Microsoft’s accounts

- *** Email address is removed for privacy *** - it's 25 GB Skydrive, it's connect to my Windows Phone 8 and has purchase history, settings to my Windows 8; generally it's set everything what's important in Microsoft Account, it's my primary account

- *** Email address is removed for privacy *** - I make it, because I want a official mail (*** Email address is removed for privacy ***)

Now I want merge this account. I want to use *** Email address is removed for privacy *** for login to WP, W8, Outlook.com, Skydrive.com, but I want to keep my 25 GB Skydrive, my purchase history and connected accounts (FB, twitter etc) in Windows Phone, my settings in W8, but I want a official email adress to. No alias, no link account, I want to have one account only. I don't need 2 account or 3, like in Google. I prefer one, from Microsoft, and every other account (Google) will be deleted. How can I do it? A woman from Microsoft Tech Support in my country can't tell me anything that it's possible or not.

PS. Sorry for my English, it isn't perfect.
