no addles won't work, since it replicates the atoms in the same positions.
I'm not sure why you aren't loading the original coordinates into Leap- the
geometry is getting lost when you only load the dimer. Maybe you can keep
trying to tell us what information you have and what you want to do- why
split into 60 mol2 files?
