For instance, I may want to keep the original definition from CHARMM for the interaction between LiCL but add a second term, which means that I will want to do the following:

No.  Function type 2 is for Buckingham potentials (Table 5.4).  These terms are 
not additive, anyway.  The purpose of [nonbond_params] is to completely override
