I see and saw the dates, and I found this topic and still find it interesting. Why start a new thread, this one's already here. I'm interested in the topic. I know its allomantically inert, I've seen Brandon's quote on this, and I know it was originally going to be "Sliver Eyes" instead of "Tin Eyes" because he was incorrectly told that Silver was part of Pewter Alloy. I know that, I get all that. However, that's reality and we're talking fantasy. We're talking fantasy of a magic in a fantasy world. We're talking of would-of's and could-of's. And just because this thread is old doesn't mean the topic is dead.
I get it, as it is right now, silver doesn't do anything, you can't even burn it. So what, this thread is about 'what if.' - Like, what would tin do, if silver had been for senses. Perhaps we'd discuss tin here instead of silver.
