As was indicated above, you won't lose your claim to your safe harbor merely by rolling your balance out of the plan.
one possible issue to consider (and I don't see think I have ever seen this brought up before), there is, most likely a distribution fee (we all live with that, it is not large, but it is still a fee).
if you roll out the balance, then at a later date receive the safe harbor and then roll that amount out I imagine you will get hit with the distribution fee again.
good luck.
