Do you know WHY they port our version from the German version? As far as translation goes, it is certainly easier if they do it from the Chinese version.
If you understand why that is, you will know that this is unlikely to happen because they will have to effectively do the same work twice in releasing such a "beta" and updating the "live" version of the server, as opposed to most "betas" which will be re-used for the "live" version of the server.

If you don't understand why that is, it's time for you to do some actual research instead of making bad suggestions.

Increasing pace of update? Sure, would be wonderful. Having a "beta" based on CN? No, that's not going to work out.
