change username link

[plongeur.com]

Hi,

My vbulletin instance is part of a wider site with external pages. These external pages have a user profile containing much more info than the vbulletin profile so i would rather have the username linked to the external profile than the vbulletin one (and have link from the external to go to the vbulletin profile for settings)

Is there any way to achieve this ?
Having a look at the template this would mean changing the "vb:url 'profile'" to get it to point to the external one, but would the vbulletin profile still be accessible ?
Can i do the change globally using replacement variables ?

I will also ask on vbulletin.org

Thanks in advance.
