Yes, that can be done. In the "Customization" part of the ASDM you can change nearly anything what controls the look and feel of the portal page. The customizations can then be assigned to your group-policy.
If you also want to have different login-pages, then you need to apply the customization to the connection-profile and the different user-groups need to use different URLs to access these profiles.
