There are no filters for trackbacks apart from the default content and
excerpt ones which won't really help.

You can't do this for pingbacks.
The ping'd site is what creates the excerpt that is shown not your site.
It works like this (taken from ):
1. Alice posts to her blog. The post she's made includes a link to a
post on Bob's blog.
2. Alice's blogging system contacts Bob's blogging system and says
"look, Alice made a post which linked to one of your posts".
3. Bob's blogging system then includes a link back to Alice's post on
his original post.
4. Reader's of Bob's article can follow this link to Alice's post to
read her opinion.
