Well, if this was possible yes. Unfortunately trade signs do not support unique items. (correct me if I am wrong) hypothetically if there was a way to do this I support it.
Im sure all you'd have to do is add all the enchanted weapons code to the trade signs item code list?
It's a lot more complicated than that. Right now tradesigns only work with item ID and item Data, enchantments are a form of "meta data" which means, it would become too complicated for the simple trade signs.
What I think of this is that it is a great idea. However it will not work with the plugin that we have. I think that the only way for this to work is to get another plugin other than the one that we have. As great as this would be I do not think it would be worth the trouble.
