Silicon does not adhere to acrylic.  Silicone does make a dandy seal though.  
However, if the view port does not fall off while you are hauling it to the 
water, it will surely pop out from the air pressure inside.  If the viewport 
were placed inside, it
would probably work. 



 Are plastic 55-gallon white citrus-fresh Mountain Dew Flavoring drums an 
approved material?

Let us know how the dive goes.  

Sounds like fun.
