Redirect Deleted Sites

OK, so I run a membership site, and it has been doing pretty well. 30 members signed up last month @ $47/m.

Here the issue. A couple members lapsed on their payments and I deactivated their sites.

Any way to have all deactivated sites (or deleted sites) automatically redirect to another site?

Preference is a plugin (WPMU developers anyone?) but will consider an htaccess or php hack as well.
