Default [Q] Kexec porting for Xperia SP

I have a question: is anyone from devs interested in porting kexec for our SPs?
It's a great way for achieving multiboot, and also a possibly ONLY way for getting custom kernel on unlock bootloader allowed:no devices. Delewer started porting it for Z1, he also made some really big progress. So, anyone working on this for C530x?
