As long as the car is inspected and passed after the fact I don’t see why you would need certification for the actual conversion. Of course that’s a big risk on the owner, but if you’re pretty sure you know what you’re doing it’s not that much of a risk

Unfortunately open sourcing is not an option without certification, cause vehucles will not be allowed to go on roads.
At least here in europe
