How to fix app resources on electron platform?

Question

Fonts

Is there any correct way to edit app resources on electron platform?
The crux of the matter is that I want to disable sub-pixel font smoothing in the css properties of the application. A simple substitution in a hex editor breaks the application.
Is it possible to somehow parse the resource files, make edits, and then put them back together?
