Can iPhone 3g use 3gs camera module

Long story short... My 2 year old son got a hold of our 2 iphones and gave them a bath in the toilet. I was able to resuscitate them both with no damage to the 3gs phone and only a dead camera module on a the other. Im getting ready to order a new camera module and was wondering if the 3gs module could be used on the 3g. I realize it probably wont magically enable video, but Im thinking maybe the larger sensor might give the 3g a picture size upgrade? The connectors look the same. Im too scared to try the 3gss module from my other phone in case it fries it...
