This is really an area specific situation to what you would do to thank an assignor. Personally nothing you sound in my opinion sounds appropriate other than maybe a thank you card and even that sounds a little much. If people do this regularly than maybe it is OK. But I would not do that unless I have heard of others do such a thing. Nothing wrong with thanking an assignor, but sending them stuff might be seen as being a suck up even if the intentions are pure.
