Hey LTown,
If you're looking to put down a batch of beer with no time for a boil and the fuss & muss then dry hopping at a later date is the way to go to add a little more somethin', somethin' to the brew. Just chuck it in loose into the primary after the krausen dies back then rack after 7-14days to the secondary or throw the hops in a cheesecloth bag in the secondary until bottling day.
The other thing I might try is different yeast such as US-05. You'll have a real American Pale Ale on your hands

Having said that you having added two cooper's ale 7g packets is definitely a great idea. Maybe even a little more depending on the date on the packet. BTW, the date is (for some crazy reason) written in the "Julien Calander". This means the day of theyear are the first three digits and the last two are the year (i.e. 03111 translates into Jan 31/2011. The older the date the more yeast you'll need.
