No,

There were reasons not to include such an option despite multiple requests.

You can hardcode widgets and plugins in skin. Manage blog settings directly in phpMyAdmin.

But I think you only need it if you have more than 10 blogs.

I'm going to make a plugin that will allow you to copy a blog's widget setup to another blog. A few days it'll take?
