Although, i've never seen him. Im pretty sure your bound to find SOMEONE who knows who you are. It doesnt necessarily have to be recognized though. I think those cosplay make you unique in a way. So that way when people come up and ask you are, you then have the chance to tell them some things about either your charcter or the anime!
I'd say Go for it! You have a long line of cosplay to do (i hope) in which you will have many opportunities to be noticed.
(Just an example) I went to a fairly small con as Yui Hirasawa, although almost everybody didnt know who i was i had one fan, really excited to see that someone cosplayed Yui.
