Well I don't now enough about Blender to talk about what mistakes you can make! In seriousness, give it a try. I don't remember if you have access to a 3D printer, you can load your model into slicing software (the tool you use to create) as a feasibility check. I use Prusa Slicer. Even without chugging through spools of plastic, you'll still learn from this.
By the way, the Argosy, Hawk, and Scoutship have all been released.
You can get all the various addons for the game for free, and also buy a legit copy of the came from the makers (if you feel $30 for a 15 year old game is acceptable) here:
