Is there any way to add map customization for the map module view? This should be as easy as adding support for the Google map styling which is handled by the API (and requires no customization on your component). It is handled by passing a Map ID that you create in the API on Google. Then in the backend of your component you would specify not only map API but Map ID (to incorporate the style). You can see this instruction here:
