We don't currently have the ability to use AUP profile avatar in SCLogin. I can add an issue to the tracker to investigate adding these features in a future release, but don't have a timeframe for you.
As mentioned in your other post, there is also not a way to switch the avatar between Social and Joomla currently depending on how the user is logged in. However, you can get around this depending on how much you want to tweak our code in the meantime. In /modules/mod_sclogin/helper.php around line 363 we have the getJoomlaAvatar method which would need to be updated to support AUP.
