How I see it the possibility is certainly there, Gallia's unique designs should be the evidence that even various gate, lane or docking ring models can be implemented. It's more like a quesiton of who has the required skill, dedication and free time to do things like that, whether it's a new model, or just a retexture or a glowmap.
I assume this case is similar to new ships and other things, if you submit a full product it might be considered and reviewed for implementation, but the dev staff got a lot of other things to work on than to add one more task to their backlog.
Unique, house-specific looks would be a nice flavour though.
