I don't see us doubling-up on the initial missions unless it becomes really trivial to catch up. Even if technology gets a 4000 year trip down to 500, even or 100, we'd probably just let the poor 4000 year schmucks go on their way. If it got down under a year maybe, but predicting what might happen if we invent FTL is a job for people who are deliberately making things up.
