CBS killed it, but some (all?) of them are working with OTOY and the Roddenberry Archive now. They had a site up a few months ago where you could walk around the bridge of nearly every iteration of every Enterprise. There were about 30 of them, including speculative designs for some early concepts for the Enterprise.
They haven’t said anything about making a full-scale Ent-D yet, but several of their videos on YouTube show glimpses of a full-scale 1701 refit.
