Mercedes Benz GLS Electric

This would be part of a what if Mercedes decided to turn the GLS into an EV like the GLA and GLB models. I suspect maybe there were some plans about such a conversion, and even a conversion for the GLE, but I guess we got the EQC instead. 

I am wondering what name this would get, would it also be EQS? or EQG? How about EQGLS? Yikes.
