I've searched and have found nothing as far as an official list. This is one of those scenarios where a home brew option is very viable. The chromatic or metallic dragon type is there to determine two things: Your elemental type, and your breath shape. So as long as your breath shape is either 30-foot cone, or 60-foot line and consists of one of the four elements: Acid, Cold, Electricity, Fire. You should be good!
Any other customization's beyond that such as picking two element types: Electric for Resistance, Acid for Weapons and breath, would be something you would have to talk to your DM about.
