Is it possible to put an alternate kernel on the usb flash, much like the usb root file system, where it will be fetched and executed if present and otherwise fall back to the one on the main system flash ?

no, unless you write your own loader. this is not so easy to do with usb.

Just a wild thought, can we make the booted kernel exec another kernel on the usb ? :)

Isn't that wild after all, it seems that is possible with 2.5 kernel with kexec, see :-
