You can use the Chimera command "swapaa" in a script. Its various options include backbone-dependent rotamer library and basically all of the other functionality of the Rotamers tool.
This page outlines how to loop through multiple proteins and execute Chimera commands:
However, I don't know how you would get the specific residue numbers into the commands. Another approach would be to generate (possibly with another script) a large Chimera command script that explicitly opens, mutates, saves to file (see the "write" command), and closes each structure.
I hope this helps,

It would be also good if rotamers for mutation residues would be backbone dependent or taken from the existing rotamer libraries (although its not essence because I can run minimization on the mutants)
