Interesting, but practical? We have this great new technology to translate into local or even personal dialects. What's the use in settling for cognateful rather than native? It's like using a car to flatten the snow so that you can walk behind it more easily, rather than riding in the car. Maybe it could be useful in creating bilingual signage where there isn't space for both languages, and understanding is optional.
