Lock Posts & duplicate posts

I use the Lock Posts Plugin in combination with the Duplicate Post Plugin http://wordpress.org/extend/plugins/duplicate-post/

So if a siteadmin lock a post its not possible to duplicate the post and edit. Yes, i can duplicate but the status "lock" is also duplicatet to the new post.

I can config the duplicate post plugin wiht custom fields i can ignore. Store the Lock Posts the data inside a custom field? Or any other solution out there for my solution?

Thanks a lot!
