Creating new character for game is fine
After all Star Wars is a tiny universe with few characters so it is hard to find original characters to add to the game. Just look at latest additions: second Cal, second Rex, second Gideon, sixs Leia... This poor universe is run out of characters already. So why not to borrow one from Space Marines... sorry, I meant why not to create brand new one. After all rebels is very tiny and unpopular faction with few know characters in it... and it is anywhey better then tenth Han...
