I used the method you described once and after a few rains found out that the container was not what I wanted. So in this case the method worked, although not with the desired result.
I would put the container really outside for some time. The bucket-method might catch some problems, but others remain. The water pressure and the weights might seal the container tighter that it would be in the wild. Also I would expect temperature differences in the bucket to be pretty limited. If a container was filled when it was hot and then (almost) tightly closed, it might actually suck in water (from rain) from the outside when it is cooler because then there is less pressure in the container than outside.
Another problem apart from the water coming into the container when that is shut is the water which comes in when it is open. I am not speaking about people signing in the rain, but about the moisture in the air. Depending on the region that can be a real problem sometimes. Logs can get damp or even wet just from that and ironically that is especially a problem if the container seals really tight.
I have mixed feelings about silica gel bags. I have seen cache contents destroyed by their remains. I can imagine that this depends really on the brand you use. Make sure they stay clean even when submerged in water, and you should be fine.
Do you know how much water such a bag can actually bind? I would image it's not that much. They are made to bind water from the air, not so much real liquid water. I could imagine one of such bags being 'full' with an ammo can-sized load of Louisiana-air in August.
