Thanks a lot Mark! I will run the system for equilibration and then try to replicate it. I will keep you guys posted.

Replicating a box that was not designed for periodicity will always have this problem. Whether the box is too small or two large, there will either be steric clashes, or vacuums that will need filling. The general solution is to equilibrate your box under PBC prior to replication. Now the box size and the atomic spacings will be plausible, and the replication will not of necessity introduce artifacts.
