Yes... the question is how much work we'd be willing to go through to
make it happen.
One approach: the kernel already contains a linker -- used for modules
-- and the bulk of the kernel could actually be composed to a "pile of
modules" that gets linked on boot. This would provide very large
amounts of randomness.
