Changing node webkit app icon on windows from cli - windows

Question

I'm currently trying to build a .bat script to autobuild my node-webkit application, and the only missing thing is changing the generated .exe icon.
I've been digging the interwebs for a while whitout finding any working solution.
So far I've tried :
Resource Hacker : I managed to change the icon using the application, but could not make it work with a script. Here is a screenshot of resource hacker with my exe
I tried the following commands :
ResHacker -modify App.exe, AppTest.exe, MyIcon.ico, Icon, 1
ResHacker -modify App.exe, AppTest.exe, MyIcon.ico, Icon, 1, 1033
ResHacker -addoverwrite App.exe, AppTest.exe, MyIcon.ico, "Icon Group", IDR_MAINFRAME, 1033
ResHacker -addoverwrite App.exe, AppTest.exe, MyIcon.ico, "Icon Group", IDR_MAINFRAME
Unfortunately, none of these created the AppTest.exe file neither did they print and error message.
RCEDIT.exe which is part of the WinRun4JS application, their home page shows an example of using RCEDIT to change the icon : RCEDIT.exe /I [YourApp].exe [YourApp].ico, this is indeed working iconwise, but it breaks the node-webkit executable and leaves me with an application running the default nodejs page. ( As a reminder, node-webkit exe are built this way
Various other applications worked fine but none of them seemed to propose a command line interface.
I feel like I'm quite close to the solution with Resource Hacker and I might have missed something obious while fiddling with it but right now I can't thing of anything else to try.
Thank you for reading and have a nice day !

Answer 1

As always, I was not trying hard enough, the right command for ResHacker was :
ResHacker -addoverwrite "App.exe", "AppTest.exe", "MyIcon.ico", ICONGROUP, IDR_MAINFRAME, 1033
Also if someone wants to dig mvanderw's solution you will need Resourcer and then run the following command :
Resourcer -op:upd -src:App.exe -type:14 -name:IDR_MAINFRAME -file:MyIncon.ico

I would rather not update the icon of the nw.exe, since it's what NodeWebKit provides. What my solution was to launch the application through a shortcut and setting the proper icon for the shortcut. That way we are using NW but not hacking it.
Note: context was windows and a setup creator like "Inno Setup", makes it easy to do.
UPDATE:
Now that I got your question, why don't you use the WinIco options of the nw-builder.
options.winIco
Extracted from the gulp task
var nw = new NwBuilder({
version: '0.12.0',
files: [ bases.dist + '**'],
platforms: ['win'],
buildDir: bases.webkit,
winIco: 'YourApp.ico',
macIcns: 'YourApp.icns'
});
