As someone who worked in the maritime industry for 20 years doing most everything you can imagine the answer is a resounding no. My first rule is to NEVER use silicone period. It’s a contaminant more than it is a sealant. I’ve never experienced it sticking to itself with any success... ever. I haven’t ever seen it not fail either.
When sealing anything the number one rule is to over prep the area you’re going to seal. This includes roughing up the surfaces and cleaning it of any oils before you continue. Removing existing silicone is extremely labor intensive. Sure, the bulk is removed easy enough but what’s penetrated into the surface area is fairly permanent creating a big problem because it won’t stick to its self let alone anything else.
