When you vote for a question to be moved to another site, the question is closed not with one, not with two, but with three grey boxes, all with a lot of links, all linking to different stuff. That is just too much visual noise:
To add insult to injury, there are two links to stackoverflow.com, but they link to different URLs: The top one links to the new question, the bottom one links to the main page.
My suggestion:
- Remove the "Locked by Community" box - for migrated questions, this is unneccessary information.
- Either remove the third box or change the link to the target site to link to the question
- Ideally, combine the third and first box so that you only have one grey box in total: "migrated to stackoverflow.com by User1, User2, User3, User4, User5 2 days ago"
Edit: Here is how I think it makes most sense:
