How to map 4scale rating model to 6box talent review

Summary:

Client is asking to implement a 6 box talent review matrix and the ratings should flow from performance. But the performance rating model used is the 4-scale rating model.

To create a 6-box matrix we have to use rating model with 3 rating and 2ratings.

Has anyone implemented this kind of requirement? And how can we map it?
