I am sorry to say that the current in-game mesh is going to be replaced due to balance issues. Nevertheless, upscaling the model will not fix the problem either and on top of that, it will look ridiculously under detailed.
Discovery is on the road to take a new course in the story-line and in-game assets which includes: optimizing system star-spheres, ship/station models, fields, & etcetera. By doing this, we increase the mods' popularity, interest, or at least that is what we strive for.
I am recently new to the Development team. I know what I got myself into but I don't pay any mind to that area. I came to put my talent into good use and do what the game needs.
EDIT: Just a reminder - the Dev team has a list of things to change and fill ship line gaps. If you are interested in knowing what list, it's here: List
