Would love to see this as well. I would like to have a separate boot image where I have some custom tweaks like ConfigMgr OSD FrontEnd, but I still want to keep my default boot image that works. Would love to be able to have an option to choose the boot image at PXE boot time.
Also love the idea to add MDOP DaRT as a possible boot option
