Yes, you could do this but only by using PHP to create the field group. You would need to set up your function to add the field group after ACF is set up add_action('acf/init', 'your_function_name')
See this: https://www.advancedcustomfields.com/resources/register-fields-via-php/
In your action you can get the values of the repeater and create the fields in the second field group.
