You just need to be aware of the fact that your N will loose potency really quickly once you opened that bottle. Your N will most likely be okay for years, if you rebottle maybe for weeks. That's the price you pay for opening the bottles. Are you sure you want to do that?
If yes, then you can of course rebottle then. Even A offered this as a method to get it through customs. Basically pouring it into a normal plastic bottle to avoid any suspicion. But as the previous poster already said, this is not recommended. If you can hide the bottles in a safe spot, that would be preferable.
