Restore a database to different databases without losing any data
You cannot backup the structure and restore that structure to another DB using SSMS; though there are third party tools that can help you, like Redgate's SQL compare which I have used previously for this. 

One suggestion is to save your TSQL scripts, and then you can apply these scripts to the other DBs by using Powershell. 

Another option is to use SQL CMS, but you will need at least one designated SQL 2008 instance.
