Generate FT_FACE from System.Drawing.Font - is it possible?

So I'm using OpenTK, and I want to substitude FreeType for the original Graphics.DrawString which is terrible and uncontrollable, yet I've found the way .NET treats system fonts convenient, such as
System.Drawing.Font font=new Font("Arial",12);
While using FreeType, FT_NEW_FACE requires full font path, but FT_New_Memory_Face reads font faces from memory. So I'm thinking, besides scanning for the original font path of a system font and pass it to FT_NEW_FACE (like in the last solution of this question http://stackoverflow.com/questions/11387564/get-a-font-filepath-from-name-and-style-in-c-windows[^], which is really tricky), is it possible to pass the font data from System.Drawing.Font into FT_New_Memory_Face, to get a FT_FACE? (Sort of like a explicit type conversion)
