Mac: Can you script toggling between the Acrobat JavaScript Editor and an external editor?

I use this folder level JavaScript to update my document level scripts. When I'm developing a document, I edit the script in Atom. I name the file the same as the PDF except with a .js extension and keep it in the same folder as the PDF. Then in my field or link properties, I use only calls to functions that are in the document level script. It makes editing super simple. When I need to update the script in the PDF, I just save it in my editor and then select "Inject Document JavaScript" from the Edit menu; no configuring the external editor, no copy/paste, no launching and relaunching the editor.

ppdf_trustedActiveDocs = app.trustedFunction(
    function () {
        app.beginPriv();
        var d = app.activeDocs;
        app.endPriv();
        return d;
    }
)
ppdf_trustedReadFileIntoStream = app.trustedFunction(
    function (sFileName) {
        app.beginPriv();
        var s = util.readFileIntoStream(sFileName);
        app.endPriv();
        return s;
    }
)
function ppdf_inject() {
    var jsFileName = this.documentFileName.split(".")[0]+".js";
    var jsPath = this.path.substring(0, this.path.lastIndexOf("/"));
    var jsStream = ppdf_trustedReadFileIntoStream(jsPath+"/"+jsFileName);
    var jsString = util.stringFromStream(jsStream);
    this.addScript("ppdf:init", jsString);
}
app.addMenuItem({
    cName: "PPDF_inject_javascript",
    cUser: 'Inject Document JavaScript',
    cParent: 'Edit',
    cExec: "ppdf_inject()",
    cEnable: "event.rc = (ppdf_trustedActiveDocs().length > 0) ? true : false;"
});

Yes. I use TextMate. The only problem is that you have to shut down the editor to get back to Acrobat, just closing the document is not sufficient.
