Profile2 registration path and ctools modal window

Hi,
I have 2 user roles with different fields in my website.. so I used profile types and profile2 registration path module to assign roles based on the registration path.. but now unfortunately I need user registration forms in popup instead of separate pages.. when I tried to use ctools modal window, by default it only renders basic registration form (without profile fields).. now creating the custom link to display form in ctools modal window.. so Is there any possibility to render the full form of corresponding user roles in ctools popup ? For example, if I have 2 roles student and non-student, I need a popup to show registration form of student profile(with ONLY student profile type fields)..

Hope I explained it correctly.. I am looking forward to your help.. Thanks in advance :-)
