I think the "gullwing" will be a very difficult MOD if there is no top frame on the doors like all the past Camaro's. The butterfly wings wont be that big of a deal. They have kits that don't involve much cutting and allow you to do "normal" door open/close or lift ou then up.
Here is one place that has a video of the automatic kind.
