Hi DjD, I'd think that your option A would be possible.

You can set the viewport background to black under Options > View > Background color.

You can set your curves to be white in MoI v2 by using Add New Style (available on the Style pop-out menu on the Styles section in the scene browser, or on the Style menu that drops down when you click in the properties panel on the style entry there) and setting it to have a white color.

Then you would also want to go to Options > Grid and uncheck "Show grid" and "Show grid axes".
