I created an app that uses a different approach.

http://www.twittertoplus.com/

It relies on people you follow having used http://gplus.to to create a Google+ name that matches their Twitter name.

Currently it finds about 20% of the people you follow.

Even if the results are not all accurate and that relying on gplus.to may not be the best solution, I get more results with it than with migratus, which is why I added a link to your app on migratus.
