It would be easier to implement this in hippie-expand because it has all
necessary infrastructure.  This could be implemented like an existing
method `try-expand-dabbrev-from-kill' added to `hippie-expand-try-functions-list',
but using `minibuffer-history' instead of `kill-ring'.

OTOH, dabbrev.el has the TODO item "Check the kill-ring when everything
else fails."  Implementing this means practically copying code from
hippie-exp.el to dabbrev.el.  I'm not sure if two identical packages
is the goal?
