I am not too against the idea now but can the other death star at least look like they do in the paintings

Do they have to?

We know what a Death Star looks like and one of them already exists as a story element.

The other one could be complete (in which case it we know how that looks) or it could be incomplete in a different way (which means someone makes models and mattes and puts them into shots).

That's not to underestimate the amount of work involved but it's not impossible it's just hard work.
