Preserve Manual Overrides

Question

Hi All,
I have a script which find  all the paragraph styles in myFind Array and change all the paragraph styles as per in the name of myChange Array.
Request:
Changing Paragraphs Styles without clear overrides or preserve local overrides like manual bold, italic etc....
script:
var myFind = ["H1", "H2", "H5"]
var myChange = ["a_H1", "a_H2", "a_H5"]
for(var i=0; i<myFind.length; i++){
     app.findGrepPreferences = app.changeGrepPreferences = NothingEnum.nothing;
     app.findGrepPreferences.appliedParagraphStyle = myFind[i];
     app.changeGrepPreferences.appliedParagraphStyle =myChange[i];
     app.activeDocument.changeGrep();
     app.findGrepPreferences = app.changeGrepPreferences = NothingEnum.nothing;
Could anyone give solution for preserve clear overrides.
Thanks in advance

Dear Trevor/Jump_Over,
I want to preserve locat format (i.e., maintain manual bold, italic etc...)
Trying Trevor script. But please find the screenshot
var myFind = ["H1", "H2"]
var myChange = ["a_H1", "a_H2"]
for(var i=0; i<myFind.length; i++){
     app.findGrepPreferences = app.changeGrepPreferences = NothingEnum.nothing;
     app.findGrepPreferences.appliedParagraphStyle = myFind[i];
      myFind[i].applyParagraphStyle(app.activeDocument.paragraphStyles.itemByName(myChange[i]), false)
//~      //app.changeGrepPreferences.appliedParagraphStyle =myChange[i];
//~      //app.activeDocument.changeGrep();
     app.findGrepPreferences = app.changeGrepPreferences = NothingEnum.nothing;
