I've never made the Canadian Blonde,but folks on the Cooper's forums have done some things with it. But you can add hops to it,just make a tea for 15mins at the beginning of the partial boil. Then take it off the heat & add everything. Do not boil the pre-hopped cooper's cans!!
If you have some DME to add,then you could add that to the boil. Then do,say,two hop additions @ 20 & 10. I;'ve seen folks add fruit to that one too.
