You should change it to Needa taking an escape pod and being intercepted, then brought to Vader :P

Couldn't disagree more.

Needa as a character has one moment to be defined: He mans up and takes responsibility with Vader. That makes us like him and makes Vader more of a jerk for killing an honorable officer.

Changing this totally alters the character, makes Needa worthy of execution (he's now a deserter) and blows Vader's best line "Apology accepted Captain Needa."
