You can make a pirate indeed. However, since at the moment there is no combat to speak of the typical pirate stuff is not really available. Some people manage to do similar stuff by scamming and otherwise getting stuff they don't own into their possession. However this generally involves more inter-person skills than any hard coded skills.
On the other hand, for RP purposes its entirely fine. I'd suggest some combat skills (projectile/non-projectile), some pilot skills, some theft/deceit and diplomacy skills.
