Product Overrides/Extensions with RequireJS

I need to provide a product specific version of ToolbarUtility.attachDocumentKeyCiteAlertWidget() (.../Platform/js/v1/RelatedInfo/KeyCite/ToolbarUtility.js). It appears however, that the ToolbarUtility and the other components that use it all use RequireJS. Is it possible to override these dependencies (e.g. ToolbarUtility) to provide product specific functionality without modifying the entire dependency chain? (The dependencies are injected with a platform path and cannot simply be overridden as normal through extension or prototype overrides for example.)
