Of course, just use the original PDB as your template and the full 
sequence, including the C and N tails plus the loop, as your target. 
Override select_atoms() if you don't want the original PDB residues to 
move. This is very similar to the "missing residues" example in the 
wiki: https://salilab.org/modeller/wiki/Missing%20residues
