It seems like it would be very easy to implement, I’ve tried manually installing the classic addon but it just errors out.
I’m not familiar with “turtle wow”. A quick search shows that it is some kind of private server. We do not have any plans to support private servers – sorry about that.
Why not it has like 10K players (only in the european PVE server + thousands in the other ones!) , and the gear is the same as classic you need to do only some minor code changes…
