Yes they could. The problems with inbreeding are caused by recessive genes being concentrated in the population. If your starting stock has no negative recessive genes and have maximum genetic diversity then you can safely breed a global population.

As the population gets large enough groups will seperate, isolating genetic materials. When those groups encounter each other and interchange individuals later on each will have their genetic diversity refreshed.
