Chances of alternate Pinephone chassis or 3D models?

I see what you mean with the antenna, that's a shame

Obviously there are fixed features with the hardware that have to be designed around, but the antenna just needs to retain the connection points. You can experiment and do something like goldplating graphene infused filament on on your own chassis. As long as the connection is solid, there's no need to stick to the official pinephone design to maintain functionality.
