Yes, you can. Everything will need to be as smooth as possible and supported on the interior to prevent breaking when you do the lay up. You will also need to learn how to use release agents and how to split the model in order to remove the forms from the finished work. It's all been done before and just takes a little education and a lot of desire.

If you want to copy a shape, one of the least dangerous ways to do it is with an aginate mold with a plaster mother mold.
Alginate is usually used by dentists and lifecasters, because it's safe to put on skin, and releases easily. (Or even in people's mouths.)
If your model can stand having something damp against it for 20 minutes, you can use alginate---usually with no release agent to mess up the detail.
You must use the alginate mold right way, because it's water-based and starts to shrink as it dries. You can usually make 2 or 3 copies of something, no more, before it distorts. I usually cast water putty (from the hardware store) in it, to get a "plaster" cast that's harder and tougher than Plaster of Paris after it dries. (But kind of soft and workable for a while when it's fresh.) From that you can make a negative mold in rubber or resin, without risking damage to your original.
