Yes... you COULD do this... but I don't see why you WOULD - because you'd suck an attack of opportunity from the fighter when you threw the dagger at him point blank.
So bascially, why would you ever want to use rapid shot in combination with melee attacks unless you either A) Absolutely positively NEEDED to do more damage to it this turn or B) Knew that there was very little chance the fighter would hit you with an AoO.
As Darklone points out:
"The only movement you can take during a full attack is a 5' step. You may take the step before, after, or between your attacks."
There's also the situation where the opponent has already made an AoO this round and you're sure he doesn't have Combat Reflexes...
