You can enter new keyboard shortcuts to replace the existing ones in Preferences -> Keyboard -> Keyboard Shortcuts -> App Shortcuts -> All Apps (or just the specific ones if you only want it in certain apps). Just be sure to use the full menu item path. So your menu item should be `Window->Move & Resize->(Left|Right|Top|Bottom|etc)`. I had to close out of the shortcuts dialog and switch to another app for it to take, but it works.
