Add Node "Boolean" that only checks mesh intersection

In geometry nodes there is a boolean mesh modifier that is very resource intensive. I would like to have the same node but only with the boundary check that gives back the intersecting vertices/edges/faces/instances in a mesh. This would allow for greater control over intersecting meshes then what boolean mesh does and would skip the step that has to calculate a mesh that fits the intersection/union/difference. I'm currently trying to make an animation that is like pacman in the movie pixels. They animate a plain mesh and "voxelize" it afterwards. This node would compress my current 6 mesh modifier workaround into 3, would achieve better results and probably cut the time for mesh construction in half
