Outlook 2007 - How to create a Right-Click Context Menu item for access within a message?

I would like to add another selection to the right-click context menu (within the email message) to Outlook 2007.  Does anyone know of any hack or registry edit that would be able to add functionality to the right click context menu WITHIN the message body?

When I right-click on a link in the open Outlook e-mail message, I would like to add an "Open with…" feature so that I can select alternate browsers to open the link.

(I have noticed that some links to websites I frequently use simply do not work with my default browser IE8)

Any other possible solutions would be greatly appreciated.
