Yes, it can be done, and there is already a mod that does it. Unfortunately I don't have the thread handy, but a quick search should lead you to it.
But be warned the game resets many variables when you reach the Unknown Planet (Leharonsomething... ). Thus the game works somewhat curious. For example, Dantooine is select- and reachable, many NPCs talk like you are still searching for the Starforge etc. Nevertheless you have the opportunity to end some unfinished quests...
