[Plugin: Widget Logic] replace widget with different widget on certain page?

Is this plugin able to control different widgets at the same time? Could I have one widget be told to not show up on certain pages, and have another widget only show up on those pages?

I have this code:
! is_page( array( 5,6,7 ) )

Which works great and deactivates that widget on those pages. However, I cannot get the reverse to work:
is_page( array( 5,6,7 ) )
I’d like this second widget to display when the first widget does not, but it seems like I’m doing something wrong. The first widget disappears on those pages, but the second does not show up.
