Have you tried the
page-cloner module?
In
this thread it is explained.
It is more or less what you would like to see.
The only problem is that is was made for WB2.6. It would need some rewriting to make it work in the WB2.7 admin tools.

Edit: Just had a quick look, the version 0.5 on the AMASP site is already adapted to work on WB2.7!
