You will definitely have a problem if you use a prmtop that has a
different number of atoms than the corresponding coordinate file; you
need to make sure your coordiantes match your topology.

I think an easier procedure might be when you generate the larger box
with leap, use the "remove" command to delete as many waters as
necessary so that it matches the smaller system. Make sure you
carefully equilibrate both endpoint systems (especially if you have
deleted some waters) before you run NEB.

Good luck!
