The questions are how and are you rewriting Hammer to finally work?Custom hammer menus

I think you could rename compilepal to vbsp.exe and run BSP only compile in Hammer to get identical resultAll you'd have to do is drop the CompilePal source code in there and reprogram the Run command to pull that up instead of the normal compile dialog. (More or less; obviously it's more complicated than I made it sound but way easier then rewriting the compile tools from scratch.) Wouldn't even have to sacrifice lightmapped props and whatever else has been introduced since 2007 that's incompatible with the old tools.
