I don't think you'll be able to do this.
The anonymous user tracking feature depends completely on a cookie (it might work with cookieless mode as well; not sure, but that would be make the problem even bigger).
So, as long as your user hasn't signed up for an account, the only way you know who this user is, is by his anonymous user ID. Once the cookie is deleted, there is no way to link up the orphaned profile with the user.
The profile information itself is not stored in a cookie, but in the aspnet_Profiles table in the database created for your application. The user's cookie is used to link that user to a specific record in that table.
