Using Bases Map View for fantasy maps

What I’m trying to do

I’m wondering if it’s possible to use Obsidian’s new map view plugin for Bases to display a fantasy map. Specifically, I’d like to use a custom image in place of the Earth map in the background of map view. I know that the Leaflet community plugin is a valid avenue to accomplish this, but I’m excited by the prospect of having my maps be readily integrated with Bases. Is there any feasible way of setting this up?

Things I have tried

I’ve done some brief rummaging through the map view plugin’s official documentation, this forum, and a broader web search, and I’m not seeing anything relevant.

Many users have expressed this requirement, may be supported in the future
