How to set profile type based on a value on registration

Hello,

One of our requirement is to set profile type based on gender value on registration. For example if user select his gender as "Male" system should set his profile type to "MaleMember". This won`t be a problem if we are only using Easysocial registration. However there are some other use cases in registration process. Which are
1) User registers via Facebook
In this case, facebook provides gender information and there is a field mapping but, how can we get this value in registration process and set the profile type according to gender on creating registration?

2) User registers via Twitter
In this case twitter does not provide gender information. Our approach would be creating a limited profile type and assign it to user on creating registration. After user successfully registers and when the user edit his profile and set his gender we need to catch the gender value and set the profile type on updating profile?

How should we approach these cases?

Thank you.
