customize each register pages for role paths

Hello,

Thank you for this great module! It allows great flexibility in having different roles and different content profiles for those roles =)

I was wondering if it is possible to have a customized registration page for each path set for each role?
With 1 role I was able to use user-register.tpl.php, but I am lost now that I would like to have two different roles and each with its own content profile registering from different paths.

So I would like:
1) guest user registering as role A to go to 'user/register/a' and creates 'content profile a'
2) guest user registering as role B to go to 'user/register/b' and creates 'content profile b'

I would really appreciate any pointers!

Thank you very much in advance
