I think this is possible, but you need to do it yourself from A to Z... you probably need to port some patches to xenon and make your own xebuild nand. You can't use JRUNNER and similar programs, because those programs don't have this motherboard in theirs configurations. The best way to do anything about it would be asking on efnet.
Also with valid freeboot image for xenon, you can have different glitch times, cause calculation time of hash changes, but it's still amazing if your xenon is booting within 30sec.
Good luck with it!
