I know many people have been looking for a way to install the 6.5 widgets if they are not included in the 6.5 ROM they are using. I found a post today that should allow you to do just that. sc00b4s7eve was the person that got it working so all credit to him.
Please see this post and let us know if it works as I have not tried it out.
