How to intersect GraphicsPaths?

[CherezZaboro]

Subj. I know one can make a region out of GraphicsPath which has methods like intersect, exclude, xor, union etc. that allow to combine regions in various ways. But can I do the same with GraphicsPath itself somehow (it doesn't have anything similar)? Regions are problematic since one can only fill it. Can't draw it and it doesn't pay attention to Graphics.SmoothingMode and Graphics.CompositingQuality. Let's say I have a polygon in a GraphicsPath. I want to cut an oval shape out of it on a side. Please help!
